Solution to a
To solve a trigonometric equation, use standard algebraic techniques (when possible) such as collecting like terms, extracting square roots, and factoring.
Our preliminary goal in solving a trigonometric equation is to isolate the trigonometric function on one side of the equation.
Calculation:
Factor the Greatest Common Factor from left side of the equation
Using the zero factor property which states that if
Solving the 1st equation and finding x values that makes it true in the interval
- By dividing 2 on both sides
- By simplifying fraction on both sides of the equation
Solving the 2nd equation and finding x values that makes it true in the interval
- By subtracting1 on both sides of the equation
- By simplifying on both sides of the equation
- By dividing -2 on both sides of the equation
- By simplifying fraction on both sides of the equation

If the problem seems to require calculus, use a graphical or numerical approach to estimate the solution. STEP 1: Consider the figure in part (a). Since this region is simply a triangle, you may use precalculus methods to solve this part of the problem. First determine the height of the triangle and the length of the triangle's base. height 4 units units base 5 STEP 2: Compute the area of the triangle by employing a formula from precalculus, thus finding the area of the shaded region in part (a). 10 square units STEP 3: Consider the figure in part (b). Since this region is defined by a complicated curve, the problem seems to require calculus. Find an approximation of the shaded region by using a graphical approach.
