- Find the exact value of cos , i.e. expressing it using only natural numbers and operations +, –-, x, /, and taking roots v. Remember to explain your answer. You don't need to simplify the final answer in this question.arrow_forwardSimplify ( sec A + csc A ) / ( 1 + tan A )arrow_forwardRewrite the expression tan x csc x cos x by changing to sines and cosines. Then simplify the resulting expression.arrow_forward
- To prove a trigonometric identity, I select one side of the equation and transform it until it is the other side of the equation, or I manipulate both sides to a common trigonometric expression. Determine whether the statement makes sense or does not make sense, and explain your reasoning.arrow_forwardWhat is sin xarrow_forwardEvaluate tan (cos(-3)) 5arrow_forward
