find out the answer the integral of cos^10 and show the solution
\[\int\limits\limits_{}^{} \cos^{10}(x) = 1/2\int\limits\limits_{}^{} (1+\cos(2x))^8 \] You will have to use the half angle formula a whole bunch of times but you can continually simplify it to this form and integrate so you will that have already reduced the power by two
The solution is pasted above. Check it out and let me know if you have a better method in Half - angle technique as you have indicated above.
