Cos x= a and Sin x =b. With the unit circle, we will now consider the right angle triangle OMP. Through Pythagorean Theorem, we get OM2+ MP2 =OP2 or a2+ b2 =1 Thus, each point on the unit circle is defined as A2+B2= 1 ...
integral belongs to a class of functions F(x)+C, where C is an arbitrary constant. Integral Calculator parses the expressions, applies integration rules and simplifies the final result. Therefore the final result of the integral computation might be different from what you expect by a constant....
Quadrant and Cast Rule As stated above, the angles other than the 90 degrees angle in a right-angled triangle are acute (i.e, less than 90 degrees). To find the value of functions for angles more than 90 degrees, we follow a set of rules known as cast rules. Let us take four axes...
