Look for either "asin" or "sin-¹" on your calculator. Press this key. (You may have to use the "2nd" key to access it.) Then type “1/2” and press Enter. The calculator gives you only the angle that is in the first quadrant. To get the other angle, you will have to figure it out by using the. first angle as a reference. a.

f' x = lim h→0 sin x cos h -1 +cos x sin h h . Next, we could use limit laws to rewrite the following statement: f ' x = sin x ∙ lim h→0 cos h -1 h + cos x ∙ lim h→0 sin h h (A) Which leaves us with two indeterminate form limits. We will need to use the Squeeze Limit Theorem. Let’s ...

cos(b − a) = cos a cos b + sin a sin b. From this formula both the sine and cosine addition formulas follow easily. Students should also know the special cases of these addition formulas in the form of half-angle and double-angle formulas of sine and cosine (Standard 11.0).
