### Algebra 2

QuestionAnswer
What is the relationship between degrees and radians? 180 = pie
sides for a 30 - 60 - 90 triangle? s, 2s, s√3
sides for a 45 - 45 - 90 triangle? s, s, s√2
ratio for sin θ opposite/hypotenuse
ratio for cos θ adjacent/hypotenuse
ratio for tan θ opposite/adjacent
ratio for csc θ hypotenuse/opposite
ratio for sec θ hypotenuse/adjacent
ratio for cot θ adjacent/opposite
how are sin and csc related? sin θ = 1/csc θ or csc θ 1/sin θ
how are cos and sec related? cos θ = 1/sec θ or sec θ = 1/cos θ
how are tan and cot related? tan θ = sin θ/cos θ or cot = cos θ/sin θ
what are the three Pythagorean trig identities? sin^2 θ + cos^2 θ = 1 1 + cot^2 θ = csc^2 θ tan ^2 θ + 1 = sec^2 θ
values of sin for unit circle? 0,1,0,-1,0
values of cos for unit circle? 1,0,-1,0,1
what is the vertical translation? it shifts the graph up or down
how to find the amplitude? absolute value of a
how do you find the period for sin and cos? 2𝜫/b
what is the formula for sine and cosine equations? y = a trig (bθ) + c
c =? midline
a =? amplitude
b =? frequency and period

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
