If find values of all other trigonometric ratios.
Step 1: Solve for the value of
Given,
Since is positive in first or third quadrant so only will be positive rest all trigonometric ratios can have positive as well as negative values.
Step 2: Solve for the value of
Step 3: Solve for the value of
Step 4: Solve for the value of
Step 5: Solve for the value of
Hence the values of all the trigonometric ratios are:
