Answer:
y' = (2x + y cosxy)/(2y + x cosxy)
Step-by-step explanation:
Using implicit differentiation:
y^2 = x^2 + sin xy
2y y' = 2x + cos xy * (xy' + y)
2y y' = 2x + xy' cos xy + y cos xy
2y y' - xy' cosxy = 2x + ycos xy
y' = (2x + y cosxy)/(2y - x cosxy)
Answer:
Step 1: Find the quotient.
Step 2: Subtract the result from 1.
Step 3: Multiply the result by –2.
Step 4: Add the result to 4 + x2.

Answer:
A
Step-by-step explanation:
Given
20 - || - 13 | + 17 |
Note the absolute value function always returns a positive value, that is
| - a | = | + a | = a, thus
= 20 - | | - 13 |+ 17 |
= 20 - | 13 + 17 |
= 20 - | 30 |
= 20 - 30
= - 10 → A
