Unformatted text preview: Combining all these, y & 2cos & & x 4 ± ± 1 is a possible equation for the graph. b. Solve the equation tan x & 3 . Solution. Since tan x is periodic (with period & ) there are infinitely many solutions, which are: x & arctan 3 ± k & & & 3 ± k & , where k is any integer. c. Decide whether the following are equal to sin & 12 or negative of it. Give your reasoning for both answers. sin & & 12 cos 7 & 12 Solution. sin & & 12 & & sin & 12 ,sincesin x is an odd function. cos 7 & 12 & cos & & & 12 & & 2 ± & sin & & & 12 ± & & sin & 12 & usesin x & cos & x & & 2 ±±...
