Is tan squared x equal tan x squared?
Yes. Both expressions are the same.
What was the formula for Pythagoras famous theorem?
x squared + y squared = z squared.
How do you solve tan squared theta - tan theta equals 0?
Let x = theta, since it's easier to type, and is essentially the same variable. Since tan^2(x)=tan(x), you know that tan(x) must either be 1 or zero for this statement to be true. So let tan(x)=0, and solve on your calculator by taking the inverse. Similarly for, tan(x)=1
What is the transformation that maps y equals sinx onto y equals the inverse of sinx?
f(x) = 1/x except where x = 0.
How does 1-sin squared x times 1 plus tan suared x equals 1?
Use these identities: sin2(x) + cos2(x) = 1, and tan(x) = sin(x)/cos(x) For clarity, the functions are written here without their arguments (the "of x" part). (1 - sin2) = cos2 (1 + tan2) = (1 + sin2/cos2) = (cos2+sin2) / cos2 = 1/cos2 Multiply them: (cos2) times (1/cos2) = 1'QED'
X squared plus 9 squared equals 12 squared?
X = √63
Is fx equals x x equals 5 a linear equation?
no, because xx=x squared, and x squared is not linear
What is Sin squared x - Cos squared x divided by 1 - Tan squared x equals cos squared x?
22
What is the solution to x squared equals x plus 6?
X squared = x+6 6+x=x squared X=6
If x equals 8 then x squared equals 64?
Yes
What does squared x equal 7?
2.645 squared equals 7. Save --------- Unclear what you're asking: If x=7, then x^2 (that is, "x squared") equals 49. or If x^2=7, then x equals the square root of 7, or about 2.64575
Why does x times x equal x squared?
Yes, x times x equals x squared.
If x squared minus y squared equals 10 and x plus y equals 5 what is x minus y?
2
X squared plus y squared plus z if x equals 7 y equals 6 and z equals 4?

What are some common math formulas?
Well pythagorus theoreum is a squared plus b squared equals c squared and circumference equals pie x diameter and area equals pie x radius squared
What is the solution to the inequality x squared equals to 25?
"x squared equals to 25" is not an inequality! You need to re-think the question!
What is x squared when x equals 10?
