Answer:
½ ln 3
Step-by-step explanation:
∫ sec²x / tan x dx
If u = tan x, then du = sec²x dx.
∫ du / u
ln|u| + C
ln|tan x| + C
Evaluate between π/4 and π/3.
ln|tan(π/3)| + C − (ln|tan(π/4)| + C)
ln|√3| + C − ln|1| − C
ln(√3)
½ ln 3
When you're counting inclusively, you subtract the numbers and add one. Here, it's 89-52+1=38 numbers.
Sum means to Add.
So the sum of d and 9 would be d + 9
Answer:
x = 2
Step-by-step explanation:
11+3 = 9x-2x
14 = 7x
x = 14/7
x = 2
Hope I helped! :)))
X // Y, Y // Z,
By inference X // Z
The third option.
