3. How would you explain to someone who has not yet studied trigonometry the
difference between an identity and an equation?
Answer:
Solving an equation means finding the value or values for which the two expressions are equal. ... An identity is an equation which is always true, no matter what values are substituted.
A trig identity is an equation that is true for all values of x;
For example:
sin²x + cos²x will always equal 1 no matter what the value of x.
There are some equations considered to be identities that are in fact not true all the time.
tan(2x) = 2tanx/(1 - tan²x) is not true when x = π/2 (right side is undefined).
A conditional equation is one that is true for a subset of the real numbers, i.e. for certain values of x, but not all.
For example:
sin²x - 1 = 0 is only true for some values of x.
sin²x = 1
sinx = ±√(1) = ±1
sinx = 1 or sinx = -1
x = sin-11 or x = sin-1(-1)
x = π/2 + 2kπ, k any integer or x = 3π/2 + 2kπ, k any integer (this can be condensed, but left this way for emphasis).

Use a net to find the surface Area of the square pyramid The height of the pyramid is 9 yes and the base sides are all 2.5 yrds and its a square as a base
Answer:
[tex]Area = 51.68yd^2[/tex]
Step-by-step explanation:
Given
[tex]h = 9yd[/tex] -- height
[tex]a = 2.5yd[/tex] --- base sides
Required
Determine the surface area
The net is not given. So, I will solve directly.
The surface area is calculated as:
[tex]Area = a^2 + 2a\sqrt{\frac{a^2}{4} + h^2}[/tex]
So, we have:
[tex]Area = 2.5^2 + 2*2.5\sqrt{\frac{2.5^2}{4} + 9^2}[/tex]
[tex]Area = 6.25 + 5\sqrt{\frac{6.25}{4} + 81}[/tex]
[tex]Area = 6.25 + 5\sqrt{1.5625 + 81}[/tex]
[tex]Area = 6.25 + 5\sqrt{82.5625}[/tex]
[tex]Area = 6.25 + 5* 9.086[/tex]
[tex]Area = 51.68yd^2[/tex]

The solution of the expression 49x¹⁸ will be 7x⁹.
What is a radical expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
The radical sign, which may be read as either the nth root of x or x radical n, expresses the root of a number. The vinculum, or horizontal line that encircles the number, and the radicand, or number beneath it, are both technical terms.
The given expression is 49x¹⁸. The value of the expression will be solved as:-
E = √( 49x¹⁸)
E = √ (7² x x¹⁸ )
E = 7x⁹
Therefore, the square root will be equal to 7x⁹.
