SOHCAHTOA Flashcards
(16 cards)
What does SIN equal?
SIN (0) = opposite / hypotenuse
What does CAH equal?
cos (0) = adjacent/ hypotenuse
What does TOA equal?
TAN (0) opposite / adjacent
What method do you use to find the adjacent? IN SOHCAHTOA
SIN
What method do you use to find the opposite? In SOHCAHTOA
COS
What method do you use to find the hypotenuse?
TAN
What are the steps to solving diagram problems?
Label the sides based on the given angle.
Decide which formula to use (SOH, CAH, TOA
Plug in the values and solve for the missing side or angles.
What methods always include the hypotenuse?
SIN and COS
What doesn’t use the hypotenuse?
TAN
If a question asks for height, what method should you use?
SIN
If the question asks for horizontal distance, what method should you use?
COSINE
If the question only gives two sides, what method should you use?
TAN
What trigonometric function should you use, you have the opposite and need the hypotenuse?
SIN
A right angled triangle has a hypotenuse of 13cm and an adjacent side of 5cm, which method do you use to find the opposite?
COS (0) = Adjacent / hypotenuse > 5/13
You know the angle is 30 degrees and the adjacent side is 10m, which method do you use to find the unknown side?
TAN (30 degrees) Opposite / adjacent > 0/10
What would you put in the calculator to find the hypotenuse?
If the opposite is 5 and the angle is 30 degrees, type
5/sin(30)
