Answer:
A
Step-by-step explanation:
Let x = Tan
dx = sec²d
sqrt(1 + ) = sec
So I = Tan(theta) * sec(theta)
but Tan(theta) = sin(theta) / cos(theta) = sin(theta)*sec(theta)
So I = integral sin(theta)*sec^2(theta) d theta
Answer A
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3x - 4y = 7 into this form
Subtract 3x from both sides
- 4y = - 3x + 7 ( divide all terms by - 4 )
y = x -
← in slope- intercept form
with slope =
• Parallel lines have equal slopes, hence
y = x + c ← is the partial equation of the parallel line
To find c substitute (- 4, - 2) into the partial equation
- 2 = - 3 + c ⇒ c = - 2 + 3 = 1
y = x + 1 ← in slope- intercept form
Multiply all terms by 4
4y = 3x + 4 ( subtract 4 from both sides )
4y - 4 = 3x ( subtract 4y from both sides )
- 4 = 3x - 4y, that is
3x - 4y = - 4 ← in standard form
