Also find a positive and negative angle coterminal with each given angle. Q. 2: Identify the closest quadrantal angles between which the following angles lies. Q. 3: Write the closest quadrantal angles between which the angle lies. Write your answer in radian measure. Q. 4: In which quadrant `theta` lie when Q. 5: Fill in the blanks. Q. 6: The given point P lies on the terminal side of `theta`. Find quadrant of `theta` and all six trigonometric ratios. Q. 7: If `cos theta =(-2)/3` and terminal arm of the angle `theta` is in quadrant II, find the values of remaining Q. 8: If `tan theta =4/3` and `sin theta < 0`, find the values of other trigonometric functions at `theta`. Q. 9: If `sin theta=(-1)/sqrt(2)` and terminal side of the angle is not in quadrant III, find the values of `tan theta,sec theta and cosec theta` Q. 10: If `cosec theta =13/12` and `sec theta > 0`, find the remaining trigonometric functions. Q. 11: Find the values of trigonometric functions at the indicated angle `theta` in the right triangle. Q. 12: Find the values of the trigonometric functions. Do not use trigonometric tables or calculator.Problem loading Video or seeking questions?
