x^2

ExplanationUsing the power rule for differentiation, the derivative of x^n is nx^(n-1). For x^2, this is 2x^(2-1) = 2x.

Equilateral

Scalene

Isosceles Right Triangle

Obtuse

ExplanationSince two angles are equal (45 degrees), it is isosceles, and because one angle is 90 degrees, it is a right triangle.

x/2

ExplanationUsing the power rule for derivatives, the derivative of x^n is nx^(n-1).

Equilateral

Scalene

Isosceles right triangle

Obtuse triangle

ExplanationIt is a right triangle because of the 90-degree angle, and isosceles because two angles are equal.

ExplanationEach number is double the previous one, so 16 * 2 = 32.

120

Explanation5! = 5 * 4 * 3 * 2 * 1 = 120.

180 degrees

270 degrees

360 degrees

540 degrees

ExplanationThe sum of interior angles of a polygon with n sides is (n-2) * 180. For n=4, this is 360.

sin(x) + C

-sin(x) + C

tan(x) + C

-cos(x) + C

ExplanationThe derivative of sin(x) is cos(x), so the integral of cos(x) is sin(x).

Infinite

ExplanationExactly two tangents can be drawn from an external point to a circle.

-1

ExplanationFor an identity matrix [[1,0],[0,1]], the determinant is (1*1) - (0*0) = 1.

ExplanationThe sum formula is n(n+1)/2. For n=10, 10*11/2 = 55.

Explanation2 raised to the power of 3 equals 8.
