This integral is mostly about clever rewriting of your functions. As a rule of thumb, if the power is even, we use the double angle formula. The double angle formula says sin^2theta=1/21-cos2theta If we split up our integral like this, int\ sin^2x*sin^2x\ dx We can use the double angle formula twice int\ 1/21-cos2x*1/21-cos2x\ dx Both parts are the same, so we can just put it as a square int\ 1/21-cos2x^2\ dx Expanding, we get int\ 1/41-2cos2x+cos^22x\ dx We can then use the other double angle formula cos^2theta=1/21+cos2theta to rewrite the last term as follows 1/4int\ 1-2cos2x+1/21+cos4x\ dx= =1/4int\ 1\ dx-int\ 2cos2x\ dx+1/2int\ 1+cos4x\ dx= =1/4x-int\ 2cos2x\ dx+1/2x+int\ cos4x\ dx I will call the left integral in the parenthesis Integral 1, and the right on Integral 2. Integral 1 int\ 2cos2x\ dx Looking at the integral, we have the derivative of the inside, 2 outside of the function, and this should immediately ring a bell that you should use u-substitution. If we let u=2x, the derivative becomes 2, so we divide through by 2 to integrate with respect to u int\ cancel2cosu/cancel2\ du int\ cosu\ du=sinu=sin2x Integral 2 int\ cos4x\ dx It's not as obvious here, but we can also use u-substitution here. We can let u=4x, and the derivative will be 4 1/4int\ cosu\ dx=1/4sinu=1/4sin4x Completing the original integral Now that we know Integral 1 and Integral 2, we can plug them back into our original expression to get the final answer 1/4x-sin2x+1/2x+1/4sin4x+C= =1/4x-sin2x+1/2x+1/8sin4x+C= =1/4x-1/4sin2x+1/8x+1/32sin4x+C= =3/8x-1/4sin2x+1/32sin4x+C

lets assume sinx = t, ⇒ (cosx)dx = dt. substituting this in the (i), we get. = ∫(1 −t2)2dt. Now using expansion of (1 −y)2 = 1 + y2 −2y, yields, = ∫(1 +t4 − 2t2)dt. = ∫dt +∫t4dt −2∫t2dt. = t + t5 5 − 2 ⋅ t3 3 + c, where c is a constant. = t + t5 5 − 2 3 ⋅ t3 + c, where c is a constant. now substituting t back gives,
