Move all terms to the left side and set equal to zero. then set the factors equal to 0 x = 13,3
As all fractions are simply an instance of division that wouldn't yield a whole number as a result, to get this answer you should simply divide all of these out.
Answer:
(-pi, 0)
Step-by-step explanation:
From the graph, we have 3 stationary point; the first one at x = 0, the second one at x = 1 and the last one at x = 2.
The function is increasing at two intervals.
The first increase is between x = -1 and x = 0.
The second increase is between x = 1 and x = 2.
From the choices give the interval that represent increase is (-pi, 0)
Answer:
Zero Slope
Step-by-step explanation:
its zero slope because it has no rise
example: rise 0 over 1
Zero slope: 0/1
undefined slope: 1/0
positive slope : 3/4
negative slope: -9/6
Answer:
θ = π n + π/2 for n element Z
Step-by-step explanation:
Solve for θ:
1 + 2 cos(2 θ) + cos^2(2 θ) = 0
Write the left hand side as a square:
(cos(2 θ) + 1)^2 = 0
Take the square root of both sides:
cos(2 θ) + 1 = 0
Subtract 1 from both sides:
cos(2 θ) = -1
Take the inverse cosine of both sides:
2 θ = 2 π n + π for n element Z
Divide both sides by 2:
Answer: θ = π n + π/2 for n element Z
