For math, science, nutrition, history Using the property that cos (-x) = cos (x) I have got: int [f (sinx)]dx = int [f (cos (x- π /2))] = int [f (cos ( π /2-x))] Looking at your first tip one would assume that the relation is that they are equal (since that yields the required result), which is obvious from a sketch of the graphs of cos (x) and cos ( π /2-x). If we let $\mu = \sin(x)$ then $d\mu/dx = \cos x \rightarrow d\mu = \cos(x)dx$. That means that $\displaystyle\int_{0}^{\pi/2} f(\sin(x))dx = \int_{0}^{0} \frac{f(\mu)}{\cos x}d\mu = \frac{1}{\cos x}\int_{0}^{0} f(\mu)d\mu$ cscX = 1 / sinX sinX = 1 / cscX secX = 1 / cosX cosX = 1 / secX tanX = 1 / cotX cotX = 1 / tanX tanX = sinX / cosX cotX = cosX / sinX Pythagorean Identities sin 2 X + cos 2 X = 1 1 + tan 2 X = sec 2 X 1 + cot 2 X = csc 2 X Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.

The answer seems to depend on how you solve it! Or are the answers related to each other?Blog post: I understand pretty well why derivative of sin(x) is cos(x) and of cos(x) is -sin(x). That makes sense, since derivative expresses the "angle of normal", I can see that from graph easily.
