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

Answer:
C. 2 -2 -3
Step-by-step explanation:
this is a combination of indicated operations
the number on the left of the indicated operation is the original set
the number '1/4' next to R shows that you need to multiply certain numbers by 1/4
the subscript on the R's shows which row the multiplication needs to be done on...
in this case it is saying that 1/4 +
will become the new
so multiply 1/4 by a number in the row and then add that to the corresponding number from
an example: (1/4 x 8) + 0 -------> 2
2 would be the new first number in the second row
