The correct answer to this question is three planes. A Spherical triangle forms from three curved arcs. It is defined as any region with three sides that are enclosed by great circle arc sides.

The angles of spherical triangles can be anywhere from 180 degrees to 540 degrees. The connecting points of the angles allow them to have sums greater than the usual 180 degrees.

The correct answer to this question is − sin x. To solve this, one would need to know about many facts that come from trigonometry. The first fact they must know is that cos( A + B) = cos A cos B − sin A sin B.

One must also know the fundamental trigonometry fact which is lim θ → 0 sin θ θ = 1 lim θ → 0 cos θ −1 θ = 0. ...

The correct answer to this question is -−csc 2 x. cot(x) stands for cotangent. cot(x) stands for cotangent. Out of the many derivatives that there are to find, cot(x) can be one of the hardest.

This is in comparison to the derivatives of sine and cosine, which are easier to find and more known. There are two steps to finding the derivative of cot(x). The first step is to use the ...

The correct answer to this question is secxtanx. There are two ways to find this derivative. The first way is to limit the derivative's definition or use the definition of the secant itself.

This is sec x = 1 cos x. We must also keep in the back of our mind the equation d x cos x = − sin x. From there, we can take several different steps to solve the derivative, as well as many ...

The correct answer to this question is sec 2 x. To be able to find the derivative of tan x, one must know the derivatives of sin x is cos x. Once one knows this, they will also know that cos x is - sin x.

Once those two things are known, the following steps and formula. d x tan x = d d x sin x cos x = cos x. cos x − sin x. ( −sin x) cos 2 x which is using the Quotient ...
