WebNov 2, 2024 · Derivative of Parametric Equations Consider the plane curve defined by the parametric equations x = x(t) and y = y(t). Suppose that x′ (t) and y′ (t) exist, and assume that x′ (t) ≠ 0. Then the derivative dy dx is given by dy dx = dy / dt dx / dt = y′ (t) x′ (t). Proof This theorem can be proven using the Chain Rule. WebTake the derivative of the previous expression to find an expression for cosh(x + y). For the following exercises, find the derivatives of the given functions and graph along with the function to ensure your answer is correct. 385. [T] cosh(3x + 1) 386. [T] sinh(x2) 387.

WebSep 7, 2024 · Find the derivative of f(x) = cscx + xtanx. Solution To find this derivative, we must use both the sum rule and the product rule. Using the sum rule, we find f′ (x) = d dx(cscx) + d dx(xtanx). In the first term, d dx(cscx) = − cscxcotx, and by applying the product rule to the second term we obtain d dx(xtanx) = (1)(tanx) + (sec2x)(x).
