Solution We will present three different approaches: Solution 1: Consider the equivalent equation ( x 2) 2 + ( y 2) 2 = 1 and the Pythagorean Identity, sin 2 t + cos 2 t = 1. We set cos t = x 2 and sin t = y 2, which gives x = 2 cos t and y = 2 sin t. mercy personal physicians mychart

WebDerivatives of the Sine and Cosine Functions. We begin our exploration of the derivative for the sine function by using the formula to make a reasonable guess at its derivative. Recall that for a function f ( x), f ′ ( x) = lim h → 0 f ( x + h) − f ( x) h. Consequently, for values of h very close to 0, f ′ ( x) ≈ f ( x + h) − f ( x) h.
