First-order differential equations chapter 1 y"-2x-ly 18x . (1+ x)y"-2xy. 13. y"+y ye"(y)' (b) solve y" x(y"- 1). 12. 20. a simple pendulum consists of a particle of m supported by a piece of string of length l. as that the pendulum is displaced through an a radians fromn the vertical and then released fr- the resulting motion is described by the initi problem 14. y"- y'tanx= 1, 0sx

answer: -1

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

sorry i just need to anwers this to get points
