Solving Equations Y1= Turn everything into the same trig function Everything on one side = 0 Factor Set Each Piece = 0 Quadratic Formula

  4. Find all the solutions ofin the interval

  5. Find all the solutions ofin the interval x Because you squared the original, check for extraneous solutions.

  6. Directions are generic! Solve 2cos u – 1 = 0 Let u = 3t cos u = 1/2 cos u =1/2 u = u =

  7. ( ) > 0 Denominator = 0 Radicand > 0 Logs Fractions Even Roots “Domain Issues” When do you have to check your work? Warning: Don’t divide both sides of an equation be something containing a variable because you can lose solutions. Square both sides
