http://faculty.up.edu/wootton/Calc3/Section14.3.pdf WebThe equation cos3t = t +1 has only one solution, t = 0, which is not a solution to cos2(t) = sin(t). So the curves do not intersect. But in general, if you discover that sint = (−1+ 5)/2 = α ... We do a follow up to OP's substitution. We need to find ∫ (sint+cost)2cos2t dt. Note that sint+ cost = 2cos(t −π/4).
