    Post Tangent equation for an equation

    The question is below:

    Find the tangent equation for siny=e^xy at (0,pie/2). Thanks. (I know the first step is to use Natural log for both sides, then I got confused.)

    so you dont use the slope formula (f'(theta)sin(theta) + f(theta)cos(theta)) /((f'(theta)cos(theta) - f(theta)sin(theta))

    You don't have to. Just remember to use the chain rule on both sides
