The Law of Sines is also known as the sine rule, sine law, or sine formula. It is valid for all types of triangles: right, acute or obtuse triangles. The Law of Sines can be used to compute the remaining sides of a triangle when two angles and a side are known (AAS or ASA) or...

Let us find the derivative of y = sin-1x. By the definition of inverse sine, y = sin-1x can be written as sin y = x. Differentiating this on both sides with respect to x using the chain rule,cos y (dy/dx) = 1dy/dx = 1/cos y ... (1)...
