List of Techniques
1) integration of powers of trig functions
2) trig substitution
3) completing the square
4) integration by parts
The following results are used widely in this area.
2 2
sin x + cos x = 1
2 2
tan x + 1 = sec x
2
sin x = (1 - cos 2x)/2
2
cos x = (1 + cos 2x)/2
sin (A ± B) = sin A cos B ± sin B cos A
cos (A + B) = cos A cos B - sin A sin B
cos (A - B) = cos A cos B + sin A sin B
2 2
ax + bx + c = a(x + bx/a) + c
2 2 2 2
= a(x + bx/a + b /4a ) + c - b /4a
2 2
= a(x + b/2a) + c - b /4a
