WebThe arcsine function is the inverse function of y = sin(x). arcsin(y) = sin-1 (y) = x + 2kπ . For every. k = {...,-2,-1,0,1,2,...} For example, If the sine of 30° is 0.5: sin(30°) = 0.5. Then the arcsine of 0.5 is 30°: arcsin(0.5) = sin-1 (0.5) = 30 ... 45° π/4: 0.8660254: 60° π/3 ... WebFind the value of given trigonometric ratio. Given trigonometric ratio: sin 75 ∘. sin 75 ∘ can be expressed as, sin 75 ∘ = sin ( 45 ∘ + 30 ∘) We know that sin ( A + B) = sin A cos B + cos A sin B. So by applying the above formula we get, sin 75 ∘ = sin 45 ∘ cos 30 ∘ + cos 45 ∘ sin 30 ∘. As, sin 45 ∘ = 1 2, cos 30 ∘ = 3 2 ...

WebCalculate sin − 1 ( sin ( 45 ∘)) without a calculator. We know that in this triangle, h 2 = a 2 + a 2. Therefore, h = a 2 + a 2 = 2 a 2 = 2 a. As h can be written as 2 a, we now know how to write an expression for sin ( 45 ∘), sin ( 45 ∘) = a 2 a = 1 2.
