A tricimal is like decimal, except the digits represent fractions with powers of 3 instead of 10. For example,16/27 = 1/3 + 2/9 + 1/27 = 0.121 as a tricimal.
I know that 16 in base 3 is 121 and 27 i
d^2y/dx^2 + 4dy/dx+4y= 8e^(2x)
I got y(x)= yh(x) + yp(x)= (A+Bx)e^(-2x)- 100/27 x^2 e^(2x)
but I dont think thats right, especially the last bit...-y + 4y + 4y = 8e^(2x)
Well its non-homogeneous so
I know that you usually cant divide by zero, but under certain circumstances, is it possible?
Let me give you 3 examples:
1. 0 / 0
2. (1 / 0) ^ 0
3. (a / 0) * 0
Please explain to me which of these cas
sigma1/n^2 (n+3)
n=1
where n goes from 1 to infinity.-its sigma 1/[(n^2)(n+3)]-Is it 1/[(n^2)(n+3)] or is it (n+3)/(n^2) ?
If it is: (n+3)/(n^2) then S = ∑1/n + 3∑1/n^2
As ∑1/n diverges(harmonic sum

this is the only problem i cant do in the
past papers for the test tomorrow. please help:)-∫ sec²(x)·tan²(x) dx = ?
Use u-substitution:
let u = tan(x) and du = sec²(x) dx

Please answer it step by step to explain how you did it.-(0.2)x+(0.75)34=50
0.2x + 25.5 = 50
0.2x = 50-25.5
0.2x = 24.5
x = 122.5-Well first you have to multiply 0.75 by 34 which equals 25.5.
