Here’s part 2 of solving trigonometric equations.
In example 1 below, the tip is to convert to one single trigonometric function – tan x.
For example 2, students are required to find two more solutions by going one more round (add 360) as they still fit in the range.
In our last example, we make use of double angle formula sin2A = 2sinAcosA to convert to one single trigonometric function.
Many students struggle in Amath trigonometry. In this short post, we have 3 simple examples where we solve basic trigonometric equations.
I hope that you learnt how to solve trigonometric equations better after this short lesson. Do look out for part 2!
