2. cos 0°
a) sin 1° b)
c) sin 90° d) tan 90°
B)cos 1°

sin 90

Step-by-step explanation:

cos (0)

Using the unit circle, we know that cos 0=1

sin 1 and cos 1  are not equal to 1

sin 90 =1

tan 90 = sin 90/ cos 90 = 1/0 =undefined

pls ask

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
