Evaluate the sine, cosine, tangent, cosecant, secant, and cotangent of t=0

Question

sin0= ?

cos0= ?

tan0= ?

csc0= ?

sec0= ?

cot0= ?

Answer 1

sin (0) =0

cos(0) =1

tan(0)= sin(0)/cos(0)

so it is

0/1 = 0

csc (0)= 1 / sin(0)

so it is 1/0 = 0

sec (0) = 1 / cos(0)

so it is = 1/1 = 1

cot(0) = cos(0) / sin(0)

it is = to 1/0 = 0
