sorry wrong posted ...

I think I skipped one step, sorry. The second step would be =1/(sin^2x+cos^2x)^2-2sin^2xcos^2x =1/1-2sin^2xcos^2x

Sorry 1/ 1-2sin^2xcos^2x

S M 7 years ago

I didn't understand the first step i think it would be 1- 2sin^2xcos^2x
1/sin^4x+cos^4x =1/1-sin^2x =sec^2x/sec^2x-tan^2x (dividing both numerator and denominator by cos^2x) Since, sec^2x=tan^2x+1 Let tan2x be t So, dt/dx=sec^2x/2 2dt=sec^2xdx so, it will come out as 2dt after putting t in place of tan2x Then after integration of 2dt U will get 2tan2x+c Please comment, if I have done something wrong in this.

When f'(×)>0 then it's strictly increasing function and if f'(×)<0 then it's strictly decreasing function.

dy/dx+y/(cosx)^2=tanx/(cosx)^2 I.F= e^(integration of 1/(cosx)^2) =e^tanx So, y.e^tanx= integ.of tanx/(cosx)^2 . e^tanx dx + c y.e^tanx= e^tanx(tanx-1) + c So the differential eqn. Is -- y = tanx-1+ c(e^-tanx) Put tanx=t in integ.

Write x^5 as x².x^3 now put 1+x^3= t then differentiate it w.r.t x then u have 3x²= dt/dx ..-> x²dx= dt/3...... Now,, integral . . . . . Now u have x^3= t- 1 -----> ¦ (t-1)dt/3 and Ur answer is 1/3 ( t²/2 -t) i.e, t²/6 - t/3 now put the value of t =1+x^3 Hope it helps u
