Solving an Equation Involving an Inverse Trigonometric Function (6.7.3) Flashcards
1
Q
• To solve an equation containing an inverse trigonometric function:
• Determine what the equation says by ‘untangling’ it. Think of the inverse trig function as
“the angle whose _______ is….” For example, think of sin^-1 as “the angle whose sine is 1/2.”
• After untangling, solve the equation normally.
• Graph the function to check that all solutions were found.
