{(x³-1)^7/3}/7 + {(x³-1)^4/3}/4 + C

Gaurav Seth 5 years, 1 month ago

given function is ∫(x³ - )^⅓ x^5.dx

let (x³ - 1) = t , and x³ = (1 + t)
⇒3x² = dt/dx
⇒dx = dt/3x²

So, ∫(x³ - 1)^⅓ x^5 * dt/3x²

⇒1/3 ∫t^⅓ (1 + t) *dt

⇒1/3 ∫(t^⅓ + t^{4/3}).dt

⇒1/3 ∫t^{1/3}.dt + 1/3∫t^{4/3}.dt

⇒1/3 + 1/3 + c

put the value of t in the above function,

The region bounded by the parabola y2 = 16x and the line x = 4 is the area OACO

The area OACO is symmetrical about x-axis 

Area of OACO = 2(Area of OAB)

Area of OACO = 

Therefore, the required area is 128/3 sq. units

Solution:

Let V be the given volume of cone.

V=Volume of cone = 

h = Height of cone = 

C=Curved surface area of cone = , where r is radius and l is slant height of cone.

C= , as l²= r²+ h²

For Maxima and Minima, derivative of C that is curved surface area should be equal to zero.

K=C²= π²r²(r²+h²)

K =

Differentiating both sides with respect to r

K' = 4π²r³ + 

Putting , K'=0

=

h=

Let A be the semi vertical angle of the cone.

Cot A =  

       = 

Cot A= 

A= 

Hence proved.

Reflexive Relation

A relation in a set A is called reflexive relation if (a,a) ∈ R for every element a ∈ A.
Example:.
Let A = {1, 2, 3, 4,5,6,7,8,9,10} and define R = {(a, b) | a divides b}
We saw that R was reflexive since every number divides itself
Let A = {1, 2, 3, 4,5,6,7,8,9,10} and define R ={(1,1),(2,2),(2,3),(3,2),(4,4)}
We saw that R is not reflexive since every number is not present in R
