Find dy
dx
1.) y = In __x2 (x+1)___
(x + 2)3
2.) y = x3 ( 3lnx-1)
3.) y = __cos6 2x__
(1-sin2x)3
4.) y = __tan 2x__
1- cot 2x
5.) y = x e (exponent pa po ng e) sin2x
6.) Arc tan...
this is the formula
R2 = R1 [ 1 + a(▲ t)] = 5.97ohms
the equation look loke this?
R2 = 4.85 [ 1 + .0038(20-x)] = 5.97ohms
i have some difficulties to find the value of x
A platinum wire having a resistance 4.85 ohms at 20degree C
is used to heat a liquid. the resistance of wire 5.97ohms after a cetain time. Determine the temperature of the liquid.
please help me to answer this.
