Trig Integrals

Example 1- Integrate (sec(2)3x)dx

Example 2- Integrate tan(2x-1/4pie)dx

Example 3- Integrate (x(2)-sin3x)dx

Double angle identities formula

Example 4- Integrate tan(2)x dx

Example 5- integrate sin(2) dx

Example 6- integrate cos(2)x dx

Use identities sin(A+B) and sin(A-B) to show that sin(A+B) +sin(A-B)= 2sinAsinB
