Question

10. A real number t is given. t = 21 ? a. Find the reference number for t. b. Find the terminal point P(x,y) on the unit circle determined by t c. Find the six trigonometric functions of t.

Answer 1

Given t=an a#) Reference number fort. 20 is lies in and quadrant si se ference number =) -2, # 30-27 > 1/3 .: Reference number for 7= 1 on th b) Termind point P(x,y) on the unit circle determined by to => x = cos ( 2 ) = - cos (+2) = -1 ay-sºn(24) - sin ( 1)- Ta mial point of 3.0) CA) Six Trigonometric functions of 7 a sin(t) = sin (9) - son(3) - sa San (t)=) => Cos (t) = cos( * )=-65(3)--2 6569=] 5) Tan Q) = Tan (24) --Tan () --13 Jan (t) = -13 7) CSC () = cse(%) - <s«CH) - ICSCC) - Pena 57 sec (t)= sec (39) -- sell+2) = -2 sect) = -2 q cot (t) = cot() --com ( 1) = -2 icot 6) - b SA. ) 2) Cos (7) = Tan (t) = cscct) - RO MIPI MIM secta cot (t) = Scanned with CamScanner
