Problem on functions- mathematics course 3 answers:

Example problem1:

To find the function of` f(x) = x^2+2x+3,` when `x=2.`

Solution:

`f(x) = x^2+2x+3`

`f(2) = 2^2+2(2)+3`

`f(2)= 4+4+3`

`f(2)=11`

Answer is `11.`

Example problem2:

To find the function of `f(x) = x^2+2x+3` , when `x=3.`

Solution:

`f(x) = x^2+2x+3`

`f(2) = 3^2+2(3)+3`

`f(2)= 9+6+3`

`f(2)=18`

Answer is `18.`

Example problem3:

To find the function of `f(x) = x^2+2x-3, ` when `x=2.`

Solution:

`f(x) = x^2+2x-3`

`f(2) = 2^2+2(2)-3`

`f(2)= 4+4-3`

`f(2)=5`

Answer is `5.`

Problems- Mathematics course 3 answers:

Example 1:

Simplify `x^2 -29xy - x + 29y. `

Solution:

The terms do not have a common factor. However, we classify that the expressions can be combined as follows:

`X^2 -29xy - x + 29y = (x^2 -29xy) - (x-29y)`

`= x(x -29y) + (-1) (x-29y)`

`= (x -29y) [x + (-1)]`

`= (x -29y) (x - 1).`

So the final answer is `(x -29y) (x - 1).`

Example2:

To solve the equation:

`(-10x - 4) - (7x - 8) = (-10x - 4) - 7x + 8`

` = -10x-4- 7x + 8`

`=-17x+4`

So the final result is `-17x+4`

Pure Mathematics Degree

Introduction to pure mathematics degree:

Pure Mathematics is planned for students with a strong mathematical environment and also helpful for higher graduate students.  The subject mathematics contains calculus, differential functions, unit measurements, number sense, groups, numerical methods, fractions & mixed numbers, vectors, algebra, geometry, algebra function, probability and statistics number using words decimals. In this article we shall discuss about pure mathematics degree. I like to share this Vector Calculus Identities with you all through my article.

Calculus problems-Pure mathematics degree:


problem 1:- Pure mathematics degree

Integrate the known expression with respect to `x: int 12x^4 - 11x^5 dx`

Solution:

Given` int 12x^4 - 11x^5 dx.`

Step 1:-

`int 12x^4- 11x^5 dx = int 12x^4 dx. - int 11x^5 dx.`

Step 2:-

`= int 12x^4dx. - 11 int x^5 dx.`

Step 3:-

`= (12x^5)/ (5) - (11x^6)/ (6) + c.`

Step 4:-

`int 12x^4 - 11x^5 dx = (12x^5)/ (5) - (11x^6)/ (6) + c.`

Answer:

`int 12x^4 - 11x^5 dx = (12x^5)/ (5) - (11x^6)/ (6) + c`

problem 2:- Pure mathematics degree

Integrate the known exponential function: ` int tan x + e^ (2x) dx`

Solution:

Step 1:-

`int tan x + e^ (2x) dx = int tan x dx + int (e^(2x)) dx`

`= int tan x dx + e^ (2x)/ (2)`

Step 2:-

`= - log (cos x) + e^ (2x)/ (2) + c`

Answer:

`- log (cos x) + e^ (2x)/ (2) + c`
