Answer:
TRUE
Step-by-step explanation:
tanθ = 1/cotθ
cotθ = 0 when θ = ±(1/2)π, ±(3/2)π, … ±[(2n+1)/2]π.
∴ tanθ is undefined when θ = ±[(2n+1)/2]π.
secθ = 1/cosθ
cosθ = 0 when θ = ±(1/2)π, ±(3/2)π, , …, ±[(2n+1)/2]π.
∴ secθ is undefined when θ = ±[(2n+1)/2]π.
The tangent and secant functions are undefined for the same values of θ.
Answer:
plot decimal values
Step-by-step explanation:
One approach is to convert them to decimal using your calculator or long division:
3/4 = 0.75
7/9 ≈ 0.78
1/2 = 0.50
2/3 ≈ 0.67
Since the number line has 0.1 increments, you can place each value in between the right increments. For instance 3/4 you place between 0.7 and 0.8. You place it halfway because 0.75 is halfway between 0.7 and 0.8. It's ok to estimate the exact location in this case.
Answer:
Step-by-step explanation:
(-5,5)...x1 = -5 and y1 = 5
(5,-4)...x2 = 5 and y2 = -4
slope = (y2 - y1) / (x2 - x1)
slope = (-4 - 5) / (5 - (-5) = -9 / (5 + 5) = -9/10 <==
