# C3 Trigonometry watch

1. Solve the equation 3cos2x+4sin2x=2, for values of x between 0 and 2pi

help please i really don't understand it at all
2. Use the Rcos(2x+a)=2 method
3. okay i did that and got tanx=4/3 which gave me 0.93 for my value of x now how do i work the rest of the values out?
4. pi + 0.93 (then keep on adding pi for the next few values, but since your range is limited to 2pi you won't need to go further than the second angle)
Similar for sin, subtract from pi
for cos, subtract from 2pi
