27 cze 2024 · To calculate the inverse of the trigonometric function, use the formula: sin(θ) = opposite / hypotenuse. ==> sin(θ) = 2 / 4 = 1 / 2. We happen to know that sin(30°) is 1/2. Hence, θ = 30°. You can also display the answer in radians, which will be 30 × (π / 180) = 0.5236 rad.
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
