Please help....
What kind of transformation is represented by sinx----> cosx?
Thank You in Advance
Hello ASD2010Look at the graphs of $\displaystyle \sin x$ and $\displaystyle \cos x$, and you'll see that they're identical in shape, but $\displaystyle \cos x$ is shifted $\displaystyle 90^o$ to the left. So the transformation is a translation parallel to the $\displaystyle \displaystyle x$-axis through $\displaystyle -90^o$.
