First we need to be in _____________ mode. (Always check before using Trig) Go to the scratchpad Hit the doc ▼ button Click 7: Settings and Status Click 2: Document Settings Find where it says “Angle:” o Choose Degree from the drop down menu Click “Make Default” Select OK DEGREES
6
Second we need to know our ________________(θ). The calculator has information stored in it for every possible angle measure, so we can easily find the trig ratio for the problems below. Find the trig button on your calculator (under ctrl) Select the trig function you wish to use Input the angle measure into the parentheses Hit enter and round your answer to the nearest hundredth Reference Angle

1. Mark the _______________ angle (θ)…usually the one given – but never the right angle! 1. Label the two given ___________ in relation to θ (opp, adj, or hyp). 1. Decide which ________________ you can use from SOHCAHTOA. 1. Write the equation, using a ______________ for the missing side. Set up a __________________ and solve for the variable (using cross multiplication) reference sides Trig function variable proportion
