Sin4x(2Sin4xCos4x)dx = 2Sin^2 4x Cos4x dx now put sin4x =t so that cos4x dx =4dt we get 8t^2dt now you can solve it easily after solving put the value of t in answer.......

Take 1+x^3= y -------(1) Then differentiate with respect to x,hence find dy/dx Then, break x^5 into x^3 and x^2 Now put value of x^3 from eq 1 And solve with respect to y.

1/2(2/5 log (2+tanx/2 upon 2-tanx/2))

Pooja Bhakar 6 years ago

Firstly we put cosx=cos^2 x/2-sin^2 x/2 and sinx = 2sinx/2cosx/2 then dividing numerator and denominator by cos^2 x/2 then we get the result in form of sec and tan after that put tanx/2=t so that 1/2sec^2 x/2dx=dt i.e. sec^2 x/2 = 2dt then solve it by partially method . I hope this answer will help you...

-log |cosx| +C
log lsecxl + c

Surya Kant 6 years ago

Integrate tanx = log| secx | +C
Take sinx/cosx.dx Take cosx=t and then -sinx.dx=dt So it will be -dt/t. Integrate it as i can't write whole answer here. If Any doubts ask.
