If sinx = 1/3 and secy= 13/12, where x and y lie between 0 and pi/2 evaluate the expression using trig identities cos(2y)

honestly bro aint no one got time to answer these dumb question just do it p***y

step-by-step explanation:

according to egenuity the answer is

step-by-step explanation:

d. 344.22

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
