First week only … Web2 jan. 2024 · Explanation: As cscx = 8, sinx = 1 cscx = 1 8 and as sinx > 0, we have 0 < x < π and 0 < x 2 < π 2 and hence x 2 lies on Q1 and all trigonometric ratios are positive. As sinx = 1 8, cosx = √1 − (1 8)2 = √1 − 1 64 = ± √63 8 and as cos2A = 2cos2A− 1 = 1 − 2sin2A, we have cosA = √ 1 +cos2A 2 and sinA = √ 1 −cos2A 2 Hence cos( x 2) = √ 1 + …

WebInverse Function. For any one-to-one function f(x) = y, a function f − 1(x) is an inverse function of f if f − 1(y) = x. This can also be written as f − 1(f(x)) = x for all x in the domain of f. It also follows that f(f − 1(x)) = x for all x in the domain of f − 1 if f − 1 is the inverse of f. The notation f − 1 is read “f ...

You'll get a detailed solution from a subject matter expert that helps … WebEvery angle greater than 360° or less than 0° is coterminal with an angle between 0° and 360°, and it is often more convenient to find the coterminal angle within the range of 0° to 360° than to work with an angle that is outside that range. Figure 1.1.17: An angle of 140° and an angle of –220° are coterminal angles.
