Answer:
No solutions
Step-by-step explanation:
To find the number of solutions, solve the equation.
15x + 6 = 15x + 9 Distribute the 3 to the (5x + 2).
(15x - 15x) + 6 = (15x - 15x) + 9 Subtract 15x from both sides.
6 = 9 Since all of the variables cancel each other out, you are left with an untrue statement, so therefore, there are no solutions to this equation.
2(cos2x - sin2x)
Step-by-step explanation:
Y = sin2x + cos2x
Differentiate wrt x
dy/dx = cos2x . 2 - sin2x . 2
= 2(cos2x - sin2x)
