Best ResponseYou've already chosen the best response.0You're pretty close. Remember that Secant is 1/Cosine, not 1/Sine.

Best ResponseYou've already chosen the best response.0Given \[(sin(x1))(tanx+secx)\] Simplify RHS \[(\sin(x1)) * ((sinx/cosx)+(1/cosx))\] Which if you add the RHS together you should get \[(\sin(x1))(1+sinx/cosx)\] And then you multiply.

Best ResponseYou've already chosen the best response.1i think it was just \[\large sinx  1\]right?

Best ResponseYou've already chosen the best response.1so it'll be \[\large \mathbf{(sinx1)*\frac{sinx+1}{cosx}}\] \[\large \mathbf{\frac{(sinx1)(sinx + 1)}{cosx}}\]
