Cos inverse of 4/5
Did you know?
WebMay 26, 2016 · Explanation: Let a = cos−1( 5 13 ). Then cosa = 5 13 > 0. a is in the 1st quadrant or in the 4th. So, sin a =+-12/13. Let b = cos−1(4 5). Then cosb = 4 5 > 0. b is in the 1st quadrant or in the 4th. So, sinb = ± 3 5. Now, the given expression is sin(a − b) = sinacosb − cosasinb = ( ± 12 13)(4 5) −( 5 13)( ± 3 5) = ± 48 65 - or + 3 13 WebCos Inverse is also written as Arccos and Cos -1 and is called an anti trigonometric function.
