$ y = $ sin $ \theta $ cos $ \theta $
It's clear, so enumerated Here. It's the way of y equals sign times Coastline of data. So your first gonna use the product rule to expand So sign do you over defeat, uh, co sign plus co sign you over D fada sign. This becomes equal to negative sign Square Plus co signed square, and we're gonna apply the double angle formula to simplify. Further. We get co sign of to data.
