Question

CalculusI Sections 3.8 and 3.9 CPA Wite using fractional exponents: Write using fractional exponents: Write with no negative or fractional exponents:x+2)-5A(xszi 2 Can you rewrite sin-1 x without the negative "exponent? Why or why not? What is the difference between an equation being written explicitly and implicitly? Give an example of each type of equation Slopes of Tangent Lines Derivatives obtained by implicit differentiation typically depend on Xand Y Therefore, the of a curve at a particular point requires both the X and -c coordinates of the point

Explanation / Answer

solution:

solving the unsolved questions of question paper

an explicit equation or a fuction is defined as the equation in which dependant variable is written in terms of independent variables

example

y=x2+2x+2

an implicit equation or a fuction is defined as the equation in which dependant variable and independent variables are written together.

equation

x2y2+2x+3y+2=0

properties of log question

logbx+logby=logb(xy)

logbx-logby=logb(x/y)

logbbk=klogbb=k

blogbx=x

logbxk=klogbx

logb1=0

next question:

y=logbx if

by=x

next queston

a)e3x+5=7

3x+5=ln7

x=1/3*(ln7-5)

b)

2x+1=20

x+1=log220

x=log220-1

d)ln(4x+5)=-2

4x+5=e-2

x=1/4*(e-2-5)
