Consider A particle performing Uniform Circular Motion. We know that its projection on diameter performs SHM. Then, if that projection starts SHM on the y axis from mean position, then $y=A\text{sin}ωt$ if that projection starts SHM on the y axis from extreme position, then $y=A\text{cos}ωt$ if that projection starts SHM on the x axis from mean position, then $x=A\text{cos}ωt$ Then What is the equation if that projection starts SHM on the x axis from extreme position?
