Which shows all the exact solutions of sin^2 x + 3cos x - 1 = 2?

Zarrin [17]

Answer:

x = 2k $\pi$ is the solution of this equation.

Step-by-step explanation:

This question is related to trigonometric equations.

The given equation is,

$sin^{2} x + 3cos x - 1 = 2$

We have to find the solutions of this equation.

Put $sin^{2}x = 1 - cos^{2}x$

$1 - cos^{2}x$ + 3cosx - 1 = 2

$cos^{2}x -3cosx+2$ = 0

For this equation only cosx = 1 is possible solution.

Cosx = 1 happens when x is a multiple of 2 $\pi$

So x = 2k $\pi$ is the solution of this equation.

Expression (5x² - 2x + 7), ( $\frac{1}{5}x^3 -\frac{7}{2}x^2 -2$ ) and (y⁵ - √(5y²) + 7) are polynomials.

<h3>What is a polynomial ? </h3>

A polynomial is a type of algebraic expression where exponents of all variables are whole number.

1) 5x² - 2x + 7

Since there are no variables raised to negative or fraction exponents,

the expression is a polynomial.

2) $\frac{1}{5}x^3 -\frac{7}{2}x^2 -2$

Since there are no variables raised to negative or fraction exponents,

the expression is a polynomial.

3) y⁵ - √(5y²) + 7

This can be re-written as

$y^5-(\sqrt{5})y+7$

Since there are no variables raised to negative or fraction exponents,

the expression is a polynomial.

4) $\frac{y^3}{3} -\sqrt{y} +2$

This can be re-written as

$\frac{1}{3}y^2 -y^{1/2}+2$

Since variable y is raised to a fraction exponent,

the expression is not polynomial.

Therefore, expression (5x² - 2x + 7), ( $\frac{1}{5}x^3 -\frac{7}{2}x^2 -2$ ) and (y⁵ - √(5y²) + 7) are polynomials.
