Who can Solve sin(-1)sin((5pi )(7)) with step by Step please )?

Answer 1

Unfortunately, the browser used for posting questions is hopelessly inadequate for mathematics: it strips away most symbols. All that we can see is "sin(-1)sin((5pi )(7))". From that it is not at all clear what the missing symbols (operators) between (5pi ) and (7) might be. There is, therefore no sensible answer. It makes little sense for me to try and guess - I may as well make up my own questions and answer them!

All that I can tell you that the principal sin-1 is the inverse for sin over the domain (-pi/2, pi/2). Thus sin-1(sin(x) = x where -pi/2 < x <= pi/2. Other solutions are x + n*pi and n*pi - x where n is an integer.

Answer 2

1. multiply 5pi x 7 = 35pi2. sine of 35 pi is the same as sin (pi ) 3. sine (pi) = 04.sin(-1) 0 is angle whose sine is 0 which is 0 or pi, ( or 2pi, 3pi, ... 35 pi etc. )
