Solving Advanced Trigonometric Equations
30 tutor-authored questions for this Ontario curriculum expectation, ordered easiest to hardest, every one with a full worked solution. Work through all 30 with your weekly-lesson access code.
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 4sin²(x)−4sin(x)+1=0 for 0≤x≤2π, recognizing a perfect square trinomial."
