Question

find the values of the constant a and b for which sin x into cosx (5 tanx + 2cotx) = a+b sin2x

Answer 1

Answer:

Step-by-step explanation:

= sinx * cosx(5tanx + 2/tanx)

= sinx * cosx(5tanx^2+2

                      ----------------

                            tanx     )    

= sinx * cosx(2sec^2/tanx)

= sinx * cosx(2/sinx)

so a=cosx and b= 2/sinx
