🦣 What Is Cos X Sin

AboutTranscript. We find the derivatives of tan (x) and cot (x) by rewriting them as quotients of sin (x) and cos (x). Using the quotient rule, we determine that the derivative of tan (x) is sec^2 (x) and the derivative of cot (x) is -csc^2 (x). This process involves applying the Pythagorean identity to simplify final results. Explanation: Suppose that sinx + cosx = Rsin(x + α) Then. sinx + cosx = Rsinxcosα + Rcosxsinα. = (Rcosα)sinx + (Rsinα)cosx. The coefficients of sinx and of cosx must be equal so. Rcosα = 1. Rsinα = 1. Squaring and adding, we get. To solve the inequality sin x > cos x we need to see which is the greater sin x or cos x on the intervals between the solutions /4 and 5 /4. The solutions can be seen if we draw the graphs of f(x) = sin x and g(x) = cos x. The graph of sin x lies above the graph of cos x on the interval /4 x 5x/4 (see the shaded area in the diagram). Answer: Derivative of cosec x cot x is -csc x (cot 2 x + csc 2 x) Example 2: Determine the second derivative of cosec x. Solution: We know that the first derivative of cosec x is -cosec x cot x. To determine the second derivative of cosec x, we differentiate -cosec x cot x using the product rule. Using product rule, we have. To compute the value of {eq}\displaystyle \cos (\infty) {/eq} we need to compute the limit. If the limit diverges then sin of infinity does not 1) $\cos^2 x + \sin^2 x = 1$ So $2 \cos^2 x = 1$ So $\cos x = \sin x = \pm \sqrt{\frac 12}$ 2) $\sin x$ is the adjacent side of a right triangle.
