In this tutorial we go over how to apply the fundamental identities in finding one trig function given another the fundamental trig identities are the fine cosine tangent secant and coseeant cotangent functions the Pythagorean identities connect Sine and cosine. tangent and secant cotangent and cosecant ASTC Can be used to determine the sign of each angular Value depending on if you are in quadrants one two three or four in quadrant for example all six trig functions are positive in other quadrants one only a pair are positive sine cosine and tangent each along with their reciprocal identity when using the fundamental identities sometimes you might have to use the quotient identities also the angular intervals that help you locate the quadrants can either be in degrees or radians. In some cases converting to degrees from radians is much better when locating the quadrants of higher degree angle you Simply have to multiply by pi divided by 180 degrees to convert you then graph your as and axis, and count by 90° 180° 27O° and 360 ° for higher angles you simply keep on rotating by 90° for each quarter circle

@kklaster

Tried out the canvas response option on @SpiralEducation & it's so awesome! Add text or drawings AND annotate an image! #R10tech

Using @SpiralEducation in class for math review. Student approved! Thumbs up! Thanks.

@ordmiss

Absolutely amazing collaboration from year 10 today. 100% engagement and constant smiles from all #lovetsla #spiral

@strykerstennis

Students show better Interpersonal Writing skills than Speaking via @SpiralEducation Great #data #langchat folks!
