Solving Advanced Trigonometric Equations
10 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest — every one with a full worked solution. Work through them free, no account needed.
Sample: the first question, solved
How many solutions does sin(x)=1/2 have on 0≤x≤2π?
📘 Worked solution
✓sin(x)=1/2 at x=π/6 and x=5π/6 within one full rotation, so there are 2 solutions.
And one from the hard end
Solve sin²(x)+sin(x)−2=0 for 0≤x≤2π.
Solution shown after you try it in practice mode.
