Write the trig. ratios for the triangle. Finding Primary Trig Ratios! sinA = cosC = tanA = You have 3 trig. keys on your calculator that will give you a "trig. ratio"for a specific angle measure. The ratio will be given to you in decimal form. Use your calculator to find the trig. ratios for the following anglemeasures. Decimal equivalents must be rounded to 4 decimal places(i.e. 0.1236 or 0.6000) cos12∘= cos30∘= Finding Primary Trig Ratios! sin5∘= sin30∘= tan22∘= tan30∘= |
