Trigonometry Equations Part Ii

An angle of 1 radian is equal to 180/π degrees in the unit circle. This is a commonly used conversion factor when dealing with radians and degrees.

To convert degrees to radians, you multiply by pi and divide by 180. Therefore, 1 Degree = pi/180 Radians.

In a full circle, there are 2π radians. Therefore, 360 degrees is equivalent to 2π radians.

The concept of amplitude does not apply to functions involving trigonometric functions multiplied together. The value of each individual trigonometric function depends on the angle x, but there is no single value that represents the amplitude of the entire expression.

The correct answers are related to the standard values of trigonometric functions and the periodicity of these functions. The values of x that satisfy the given statements fall on specific angles where the trigonometric functions have defined values.

To evaluate Tan(Sin^(-1)(3/5)), we first find Sin^(-1)(3/5) which means finding an angle whose sine is 3/5. This corresponds to the angle alpha where opposite side is 3 and hypotenuse is 5. Applying Pythagorean theorem, we find the adjacent side as 4. Therefore, Tan alpha = 3/4.

The correct period for the graphs of csc x and sec x is 2? because the period of the csc x and sec x functions is equal to 2π.

The cosecant (csc) and secant (sec) functions are reciprocals of the sine (sin) and cosine (cos) functions respectively.

The amplitude of secant and cosecant functions is considered to be zero because these functions do not have a specific maximum or minimum value in the range of y. Therefore, they do not exhibit any periodic behavior that would define an amplitude.

The correct answer provides the relationship between x and y when y = tan^-1x or y = arctanx. The incorrect answers provide misleading interpretations of the given equation, leading to incorrect conclusions.

The correct answer can be determined by understanding the standard forms of trigonometric functions. In this case, the amplitude is the coefficient of sin, the period is (2π)/absolute value of the coefficient of x, and the phase shift is determined by finding where the expression inside the sin function equals zero.

The period of both tan x and cot x functions is pi. This means that after every pi units, the function repeats itself.

The tan curve passes through the Origin, which is where the x-axis and y-axis intersect in the coordinate plane. It does not pass through the X-axis, Y-axis, or Infinity.

When the tangent function is zero, it means that the sine function is zero while the cosine function is not zero. In this scenario, the cotangent function becomes undefined as it is the reciprocal of the tangent function.

The functions Cotangent (Cot) and Tangent (Tan) do not have an amplitude as they do not have a periodic nature like the sine and cosine functions.

The correct formulas for Amplitude, Period, Phase Shift, and Vertical Translation in a trigonometric function are crucial to understand the properties of the function and its graph. It is important to differentiate the correct formulas from the incorrect ones to accurately analyze sinusoidal functions.

The correct answer is y = cot x, which represents the cotangent function in trigonometry. Cotangent is the ratio of the adjacent side to the opposite side in a right triangle.

In this question, each angle's measure is being represented as a multiple of pi/6. The correct sequence is 30 degrees = ?/6, 150 degrees = 5?/6, 210 degrees = 7?/6, 330 degrees = 11?/6. The incorrect answers provided do not follow this pattern and therefore are incorrect.

The correct function to graph in this case is sec x because secant x is the reciprocal of cosine x. While the incorrect answers csc x, tan x, and cot x are the reciprocals of sine x, tangent x, and cotangent x respectively.

The periods of trigonometric functions represent the intervals at which the function repeats, completing one full cycle. In this case, sin x and cos x have a period of 2π radians, while tan x, csc x, sec x, and cot x have a period of π radians.

In the cosine function, the period is 2π, hence the first midpoint in quadrant I occurs at π/2, which corresponds to the value of cos(π/2) = 1.

The first midpoint on the x-axis in Quadrant I for y = 6sin(x) occurs at x = π/2, where the sine function has a zero point and the value of 6sin(π/2) is 6*1 = 6.

Inverse tangent (Tan-1) function has a restriction that the output is limited to angles between -90 degrees and +90 degrees due to the nature of the tangent function.

When evaluating Sin-1(-1/2), the correct answer is -30 degrees (or -π/6) because the inverse sine function returns values between -90 and +90 degrees. The incorrect answers provided do not align with the correct calculation and the restriction set for Sin-1(-1/2).

The correct values for sin(x) are obtained by evaluating the sine function at the specified x-values in radians, which are 0, ?/2, ?, 3?/2, and 2?. The correct answers represent the sine values at these specific x-values according to the sine function graph.

The correct restrictions for sin-1, tan-1, and cos-1 are as follows: Sin-1: -90 and +90 degrees (-π/2 and 3π/2), Tan-1: -90 and +90 degrees (-π/2 and 3π/2), Cos-1: 0 and 180 degrees (0 and 2π). Each trigonometric function has specific ranges within which they are defined.

The expressions Cos-1 4/5, tan-1, and sin-1 are all inverse trigonometric functions that return an angle as their output.

The question asks for two specific functions that are Cos x and Sec x. The incorrect answers provided do not match the correct combination of functions.

The correct function for tangent is y = tan x, where tan x = sin x / cos x. The other functions, sin x, cos x, and sec x, represent sine, cosine, and secant functions respectively.
