Question

34. If a and ß are two solutions of the equation a tan x +b secx = c, then find the values of
sin (a + b) and cos (a + b).​

Answer 1

Answer:

using a and b as values of x satisfying original equation.

Step-by-step explanation:

I have found values of sin a and cos a.

we can now use formulae for sin(a +b ) and Cos(a + b) for a lengthy calculation . thanks for very good question.
