Step 5: If a sin function is provided instead, a graph will be provided We cannot emphasize enough the importance of correctly calculating operations involving sine, as those will appear literally everywhere. sin and cos formula Sine and cosine are two very close cousins, if not sisters. There...
sin-1x + cos-1x = π/2, when x ∈ [-1, 1] sin-1(2x √1 - x²) = 2 sin-1x, when -1/√2 ≤ x ≤ 1/√2 and sin-1(2x √1 - x²) = 2 cos-1x, when 1/√2 ≤ x ≤ 1Derivative of Inverse Sine Let us find the derivative of y = sin-1x. By the definit...

How do you prove sin^2(x) + cos^2(x) = 1? How do you solve sin^2(x) - 2sin(x) = 0? What is the difference between sin^2x and sinx^2? Given that sin^2x = \frac{4}{13}, what is the cos^2x? When does sin^2(x) = 3/4?
No, sin 45 and cos 45 do not refer to the same trigonometric function since the trigonometric ratios of sine and cosine are derived differently from a right-angled triangle. However, when solved, they give the same answer (or mathematical value of 12). From the circle, we can understand ...
