Find the exact value of $\sin \theta, \cos \theta,$ and $\tan \theta$ using reference angles. $$\theta=-930^{\circ}$$

Chapter 5

An Introduction to Trigonometric Functions

Section 7

Trigonometry and the Coordinate Plane

you were looking to solve for the sign Cosan intention of data there is equal to negative 9 30 You know the negative 93 d is co terminal with the angle 1 50 degrees which is in quadrant two, where X is negative and why is positive? So that means that in question to sign is positive co signers. Negative intention is negative. And to find out a reference single me dio they don't reference is equal to 1 80 minus 1 50 which is you go to 30 degrees so Sandra theta becomes the positive side of 30 Go Center later becomes the negative coastline of 30 and change it off later becomes a negative tension of 30. Sign of 30 we know is 1/2. Can we have negative route through? You were too. Do we have negative route three over three

In mathematics, a continuous function is a function for which sufficiently small changes in the input result in arbitrarily small changes in the output. Otherwise, a function is said to be a discontinuous function.
