Answer:
i)
ii) n = 33
Step-by-step explanation:
For this question you can actually focus on the sine, and forget about the e power. The x-coordinates of the extremes of the curve will be the same as for y=sin(4x)
i) equivalent to solving sin(4x) = -1, so 4x = 3/2 pi, x=3/8 pi
ii) The Tn values are at x = (n·π - π/2)/4
solving (n·π - π/2)/4 > 25 gives:
n > 1/2 + 100/π, so n > 32.331, but n must be integer, so we get n=33
Replace x with 2+i and solve
Remember that i is the square root of -1
My phone automatically capitalizes I, so don’t be confused by that!
y=(2+I)^2 + 3(2+I) +5
y=4+4i-1+6+3i+5
y=7i+14
Answer:
B) 12 +n
Step-by-step explanation:
"More than" is a key word.
Whenever you see more than, you are adding.
Your answer is 3 raised to 4 that is 3^4.
Hope this helps :)
