Math 110 5. (8 points) Find the period and graph one period of y = tan 2x Fall 2019 6. (12 points) Find the exact value of 5) sin cos 31

Answer 1

- Ane 6 y = tanan The period of y= fan ax 1 . Graph for the curre is 7 . y is a -75 This is I This is a rough grough for y-teman. And 6 a Cone ( 3 ) . Cox+(-x) = - Cost (%). => const {) = - Con" () => Con ' 3) = 1- Cos'" (d) sive) { 27- Con=4 (Con.) . love the same - = - {.. Con" (Conx)= x > Con- ( ) = 3

b) Sim (con let Con't get So, equation © Conx = 2 ans becomes : 1 Sin (2) Nowo, we want Here, Cor x to find the value of Sin x. = 2 25 lwe know that :- Sin²n = 1- Cox²x =) Sin'x = level So, Put a costau in above : sin (love s9] = is

0 c in Cox-i (sin 27 ) - a sin ax = sin(x-7) - Son (3) = 3 So, eqr o becomes: - - Coxl/sin 2) 1 = Coni ( ) = Con" (Cox-7) S. CORA - J şi con Icons \- x3 ga (Sin cate)
