Answer:
1-cos2A/sin2A
=(1-cos^2 A+sin^2 A)/(2sinAcosA)
=(sin^2 A+sin^2A)/2sinAcosA
=2sin^2 A/2sinAcos^2 A
=sinA/cosA
=tanA
Answer: it would be 1.578 times 10^-6125
Or 1.578 times 10^-1230
39 degrees. All angles must add up to 180 and the two acute angles equal each other because of the type of triangle it is!
Answer:
Function 1.
Step-by-step explanation:
The rate of change of Function 2 = (18.75 - 14.25)/ (5 - (-1))
= 4.5 / 6
= 3/4 or 0.75.
For Function 1 it is 5/6 or 0.83
So Function 1 has greatest rate of change.
