The integral of (sin x) (cos x) was asked in calculus class. Albert thought about the problem in terms of a u-substitution. He set u = sin x so that du = cos x dx. He then solved the problem as follows to get an answer of (1/2)sin 2 x + C.

How do I calculate the integral of 1/cosx -sinx? The easiest way to perform this sum would be to multiply and divide by square root of 2 in denominator to convert it to a term of sin function. Another way,probably the longest one,would be to use the half angle tangent formula and then substituting tan x/2 for t.

For each of these, we simply use the Fundamental of Calculus, because we know their corresponding derivatives. csc (x) = -csc (x)cot (x) , sec (x) = sec (x)tan (x) , cot (x) = -csc 2 (x).

Integral of sine \({\large\int ormalsize} {\sin x\,dx} = – \cos x + C\) Integral of cosine \({\large\int ormalsize} {\cos x\,dx} = \sin x + C\) In integral calculus, integration by reduction formulae is method relying on recurrence relations.It is used when an expression containing an integer parameter, usually in the form of powers of elementary functions, or products of transcendental functions and polynomials of arbitrary degree, can't be integrated directly.
