Geometric interpretation: Rotate the right triangle. The projected length of the √ 2 hypothenuses will vary following a sinusoid. It's correct so far, but I don't think it helped. Expand out the bracket on the LHS and see if you recognize anything. Solve for a variable, factor, expand, evaluate fractions, linear equations, quadratic equations, inequalities, systems of equations, matrices. Oct 28, 2023 ... I'm just confused as to why sinxcosx is rewrote into a double angle then it's divided by 1/2. I thought double angles were only 2sinxcosx for sin(2x).
