I need to simplify this trigonometric expression. The answer will be given, but please help me with the process.
1 answer:
Answer:
Step-by-step explanation:
I've attached a pic, I used y for sin(theta) and x for cos(theta). Shows all steps. See image.
Step 1: use "factoring sum of cubes" to factor the numerator.
Step 2: in the trinomial, in the numerator, rearrange terms to use the sin^2 + cos^2 = 1 .
Step 3: cancel that factor with the denominator.

Given:
The point, (4, -3)
The line,
To find an equation in slope-intercept form for the line that passes through (4,-3) and is parallel to the given line:
The slope of the line is,
Since the given line is parallel to the new line, so the slope will be same for the both.
Using the point-slope formula,
Substitute the point and slope we get,
Hence, the equation in slope-intercept form for the line is,
