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 substituti
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.
sin 3(x) cos 2 [integral] sin x dx = -cos x + C Proof, [integral] csc x dx = - ln|csc x + cot x| + C Proof. [integral] cos x dx = sin x + C Proof, [integral] sec x dx = ln|sec x + tan x| + C Integrating this to get v gives v = –cos(x). So our integral is now of the form required for integration by parts. ∫ x sin(x) dx.
Proofs. For each of these, we simply use the Fundamental of Calculus, because we know their corresponding derivatives. cos (x) = sin (x), cos (x) dx = sin (x) + c. -sin (x) = cos (x), sin (x) dx = -cos (x) + c. sec ^2 (x) = tan (x), sec^2(x) dx = tan (x) + c. The integral of (sin x) (cos x) was asked in calculus class. Albert thought about the problem in terms of a u-substitution.

∫ ex cosx dx. Get answer: int (sin x+ x cos x ),(x sin x)dx. Get answer: int_(0)^(pi,,2) (sin x) , ((sinx + cosx)^(2) ) dx = inte^x((1+sinx),(1+cosx))` 1+sin x)dx equals-1+cos x)Stor to 10(2) excot (x,2) +. Ek. COSX sinx dx.
(2 + sin(x))y + cos(x)y = (2 + sin(x))y + (2 + sin(x)) y = ((2 + sin(x))y) vilket ger direkt (OBS att F(x) = x + 1 tas som en primitiv till f(x)=1.) (2 + sin(x))y = ∫ ln(x + 1)dx

Proofs. For each of these, we simply use the Fundamental of Calculus, because we know their corresponding derivatives.
The integrals may be evaluated indirectly via auxiliary functions and (), which are defined by Si ( x ) = π 2 − f ( x ) cos ( x ) − g ( x ) sin ( x ) {\displaystyle \operatorname {Si} (x)={\frac {\pi }{2}}-f(x)\cos(x)-g(x)\sin(x)}
