Did you know?
WebA You only know the cosine of the angle: cos (2 * phi) = 2 * cos^2 (phi) - 1 B. You only know the sine of the angle (you can actually calculate cos (2*phi) by just knowing the sine: cos (2 * phi) = 1 - 2 * sin^2 (phi) In contrast, the sin of a product is not nearly as exciting: sin (2*phi) = 2 * sin (phi) * cos (phi) ( 4 votes) Show more...

The derivative of a function describes the function's instantaneous rate of change at a certain point - it gives us the slope of the line tangent to the … WebMar 27, 2024 · Therefore cos D = 3 5 and sin D = − 4 5 which makes the reference angle is − 53.1 ∘ or − 0.927 radians. Since cosine is positive and sine is negative, the angle must be a fourth quadrant angle. D must therefore be 306.9 ∘ or 5.36 radians. The final answer is 3 cos 2 x − 4 sin 2 x = 5 cos ( 2 x − 5.36).
