sin(θ) = cos(θ) = tan(θ) = Trig Ratios Review
First we need to be in _____________ mode. (Always check before using Trig)Go to the scratchpadHit the doc▼ buttonClick 7: Settings and StatusClick 2: Document SettingsFind where it says “Angle:”Choose Degree from the drop down menuClick “Make Default”Select OKCalculators! DEGREES
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 useInput the angle measure into the parenthesesHit enter and round your answer to the nearest hundredthCalculators!Reference Angle
Practice***Round to the nearest hundredth
Mark the _______________ angle (θ)…usually the one given – but never the right angle! Label the two given ___________ in relation to θ (opp, adj, or hyp). Decide which ________________ you can use from SOHCAHTOA. Write the equation, using a ______________ for the missing side. Set up a __________________ and solve for the variable (using cross multiplication)Finding a Missing Sidereference sides Trig function variable proportion
Mark the reference angle: θ = 34Label the given sides in relation to θ: opp. and hyp.Decide which trig function to use: SineWrite the equation using x for the missing sideSet up a proportion and cross multiply
Mark the reference angle: θ = 75Label the given sides in relation to θ: adj. and hyp.Decide which trig function to use: CosineWrite the equation using x for the missing sideSet up a proportion and cross multiply
