Q Find all older derivatives



y = X^4/2 = 3/2X^2 -X



y4 = 2X^2 - 3 x ^ 1 - 0

y4 = 4X^1 - 3 -0

y4 = 7

thats not so much a question as it is random keystrokes... ;)

Q Find all older derivatives



y = X^4/2 = 3/2X^2 -X

Do you mean y = (1/2)x⁴ - (3/2)x² - x?

y4 = 2X^2 - 3 x ^ 1 - 0

What is y4 supposed to be? Since you have taken the derivative, this should be y'. Of the three terms you differentiated on the right side, only one is correct: d/dx[-(3/2)x²] = -3x. The other two terms have errors.

y4 = 4X^1 - 3 -0

y4 = 7
