Does your teen struggle to keep signs straight in the coordinate plane system when it comes to trigonometry functions?
I have a mnemonic for you today that will help your teen know which functions are positive.
It’s short and simple so it can be memorized easily.
Here it is.
Trigonometry Mnemonic
Here’s a way for teens to remember which trig functions are positive in each of the four quadrants of the coordinate plane.
First, let’s look at the quadrants.
Quadrant I: All functions are positive.
Quadrant II: Only sine is positive.
Quadrant III: Only tangent is positive.
Quadrant IV: Only cosine is positive.
Now here’s an easy phrase to remember that will cue teens in to each quadrant. Notice the bold word or letters.
All seniors take calculus.
That’s it. Easy peasy.
