WebMath; Calculus; Calculus questions and answers; 3. Find the exact value of each expression. a. \( \csc \left(\frac{\pi}{3}\right) \) b. \( \sec \left(\frac{3 \pi}{4 ... Web7 years ago. The easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into those last two equations and solve for sin θ/2 and cos θ/2. WebAfter you've mastered the derivatives of the basic trigonometric functions, you can differentiate trigonometric functions whose arguments are polynomials, like sec (3 π 2 − x) \sec\left(\dfrac{3\pi}{2}-x\right) sec (2 3 π − x) \sec, left parenthesis, start fraction, 3, pi, divided by, 2, end fraction, minus, x, right parenthesis. can minecraft be played on ps5
