SORRY i really don't know how to put these symbols such as Integral sign ,
1. Integrate for SEC X/3 DX FROM (-PI) --> (PI)
( I think these problems are using substitution to solve but I just can't work it out like how to put them together to solve.
2. Integrate for csc(x-pie) dx from ( from 3pi/2 ---> 7pie/4 )
3. Integrate for dx/√ of (1- 9x^2 ) from ( 0 ---> 1/6 )
4. Integrate for 6 DX / X √ OF 25X^2 -1 FROM (2(5√3) ---> 2/5
5. Integrate for sec piex DX from ( 0 ---> 1/4 )
Please tell me how to start and I can solve the rest . Thank you
