Integral of cot xis, ∫ cot x dx = ln |sin x| + C Apart from these, there are some other rules that involve a combination of trigonometric functions. ∫ sec2x dx = tan x + C ∫ cosec2x dx = -cot x + C ∫ sec x.tan x dx= sec x + C ...
The following results illustrate the need of integration: 1. Trigonometric identity:cos2(x)=1+cos(2x)2. 2. Move the constant out:∫b⋅f(x)dx=b⋅∫f(x)dx. 3. Common integration:∫cos(u)du=sin(u). 4. The sum rule:∫f(x)±g(x)dx=∫f(x)dx±∫g(x)dx...
