integrate `int_0^(2pi) e^x . sin (pi/4 + x/2) dx`A. `(-3sqrt(2))/ 5 (e^(2pi)-1)`B. `(3sqrt(2))/ 5 (e^(2pi)-1)`C. `(-3sqrt(2))/ 5 (e^(2pi)+1)`D. `(3sqrt(2))/ 5 (e^(2pi)+1)`
`int_0^1(cos^(- 1)x)^2dx`A. `pi/2 +1`B. `pi/2-1`C. `pi+2`D. `pi-2`
`int_0^pisin^3x(1+2cosx)(1+cosx)^2dx`A. `8/3`B. `(-8)/3`C. `4/3`D. `(-4)/3`
If `int_0^a3x^2dx=8,`find the value of `adot`
The integral `int_0^pisqrt(1+4sin^2x/2-4sinx/2dx)`equal(1) `pi-4`(2) `(2pi)/3-4-4sqrt(3)`(3) `4""sqrt(3)-4`(4) `4""sqrt(3)-4-pi/3`A. `pi-4`B. `4sqrt(3)-4`C. `(2pi)/3 -4-4sqrt(3)`D. `4sqrt(3) - 4 - pi/3`
Evaluate :`int_0^(pi/2)(dx)/(1+sqrt(tanx))`A. `(3pi)/2`B. `(3pi)/4`C. `pi/2`D. `pi/4`
`int_0^(pi//2)(theta/sintheta)^2d theta=`A. `pi/(log2)`B. `log 2`C. `pi log 2`D. `pi`
