Answer:
B
Step-by-step explanation:
Answer:
f ⁻¹ (-2)=3
f ⁻¹ (1)= 0
Step-by-step explanation:
inverse functions are switching x and f(x) coordinates so f ⁻¹ (-2)=3 and f ⁻¹ (1)= 0
Step-by-step explanation:
Let a = 8 and b = 11. Using the law of cosines, we can write
Now we're going to use the sine to find
or
or
2pi/3 has the same Sin, Cos, & Tan as pi/3 in QI except for the SIGNS.
2pi/3 is in QII so Cos is negative and Tangent is negative, Sine is still positive.
Sin 2pi/3 = √(3) / 2
Cos 2pi/3 = -1/2
Tan 2pi/3 = -√3
