# Summary of Chapter 2 | Trigonometry | Type of Trigonometry Equation | June 2017

## Good algebra will also be required in Solving BASIC Trigonometry Equation. For example,

- 2 sin
*Î˜*= - 0.8660 is similar to 2*x*= - 0.8660**where we need to move the number 2 from LHS to RHS,**

which becomes sin*Î˜*= - 0.8660÷2 is similar to*x*= - 0.8660÷2 *sin*^2*Î˜*= 0.5 is similar*x*^2 = 0.5**where we need to move the power of 2 from LHS to RHS,**

which becomes*sin**Î˜*^{ }= ±√ 0.5 is similar*x*^{ }= ±√ 0.5*(note that ± appears when we move the power of 2 from LHS to RHS)*

*LHS = Left Hand Side , RHS = Right Hand Side
