Y = cot2(sinФ)
dy/dФ = d/dФcot2(sinФ)
dy/dФ = -cosec²2(sinФ) d/dФ2(sinФ)
dy/dФ = -cosec²2(sinФ) 2cosФ
dy/dФ =-2[cosФ][cosec²2(sinФ)]
Answer:
21.875 percent decrease
Step-by-step explanation:
Answer:
3.84 feets
Step-by-step explanation:
Given that:
θ = 88°
Radius, r = 2.5
The length of section of the wire, L ; Length of an arc
L = θ / 360° * 2πr
L = 88/360 * 2*π*2.5
L = (88/360) * 15.707963
L = 3.8397
Length of section of wire = 3.84 feets
<span>One type of proof is a two-column proof. It contains statements and reasons in columns. Another type is a paragraph proof, in which statements and reasons are written in words. A third type is a flowchart proof, which uses a diagram to show the steps of a proof.</span>
Answer:
188 cm^2.
Step-by-step explanation:
This consists of 3 pairs of rectangles
= 2 * 4*7 + 2 * 4*6 + 2 * 6*7
= 56 + 48 + 84
= 188.
