i am very sorry if im wrong
Answer:
see explanation
Step-by-step explanation:
Using the chain rule and the standard derivatives
Given
y = f(g(x)) , then
= f'(g(x)) × g'(x) ← chain rule
(tanx) = sec²x ,
(cotx) = - csc²x
(c)
y = tan
= tan
= sec²
×
(
)
= sec²
× ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
![x^{-\frac{1}{2} }](https://tex.z-dn.net/?f=x%5E%7B-%5Cfrac%7B1%7D%7B2%7D%20%7D)
= sec²
× ![\frac{1}{2x^{\frac{1}{2} } }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2x%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D%20%7D)
= ![\frac{sec^2\sqrt{x} }{2\sqrt{x} }](https://tex.z-dn.net/?f=%5Cfrac%7Bsec%5E2%5Csqrt%7Bx%7D%20%7D%7B2%5Csqrt%7Bx%7D%20%7D)
(d)
y = cot(1 + x)
= - csc²(1 + x) ×
(1 + x)
= - csc²(1 + x) × 1
= - csc²(1 + x)
Answer:
9.1x- 10000
9.1 x 10^-4
Step-by-step explanation:
b
X=5
Y=8
Z=8
3x+2y-z=23 --> z=-23+2y+3x
Y=8
Substitute for -2y+4z=16
-2(8)+4(-23+2(8)+3x)=16
-16-28+12x=16
-44+12x=16
12x=60
X=5
Substitute known y and x values into z=-23+2y+3x
Z=-23+2(8)+3(5)
Z=-23+16+15
Z=8
