$\frac{d}{dx}\left(\sin\left(x\right)\right)+\frac{d}{dx}\left(\sec\left(xy\right)\right)$
Learn how to solve problems step by step online. Find the derivative d/dx(sin(x)+sec(xy)+-3) using the sum rule. The derivative of a sum of two or more functions is the sum of the derivatives of each function. The derivative of the sine of a function is equal to the cosine of that function times the derivative of that function, in other words, if {f(x) = \sin(x)}, then {f'(x) = \cos(x)\cdot D_x(x)}. Taking the derivative of secant function: \frac{d}{dx}\left(\sec(x)\right)=\sec(x)\cdot\tan(x)\cdot D_x(x). The derivative of a function multiplied by a constant is equal to the constant times the derivative of the function.
