What is the value of the integral of e^x?

• e^x - C

• e^x * C

• e^x / C

• e^x + C

Solve the equation: 3x^2 + 5x - 2 = 0

• x = 2 or x = -1/3

• x = 0 or x = -5/3

• x = 4 or x = -1/6

• x = 1/3 or x = -2

Find the derivative of f(x) = 3x^4 - 2x^3 + 5x^2 - 7x + 9

• f'(x) = 12x^4 - 6x^3 + 10x^2 - 7x

• f'(x) = 12x^3 - 6x^2 + 5x - 7

• f'(x) = 12x^3 - 6x^2 + 10x - 7

• f'(x) = 12x^3 - 6x^2 + 10x - 9

What is the value of the limit lim(x->0) (sinx/x)?

• sin(0)

• 2

• 0

• 1

Solve the differential equation: dy/dx = 2x + 3

• y = 2x^2 + 3x + 1

• y = 2x^2 + 3x - C

• y = 2x^2 + 3x

• y = x^2 + 3x + C

Find the value of the sum: 1 + 2 + 4 + 8 + 16 + ...

• The sum of an infinite geometric series with a common ratio |r| < 1 is given by S = a / (1 - r), where a is the first term and r is the common ratio. In this case, a = 1 and r = 2. So, the sum S = 1 / (1 - 2) = -1.

• S = 1 / (1 + 2) = 1/3

• S = 1 / (1 - 4) = -1/3

• S = 1 / (1 - 8) = -1/7

What is the value of the complex number i^i?

• 3.14

• 0.20788

• 1.414

• 0.5

Solve the inequality: 2x + 5 > 3x - 2

• x = 7

• x > 7

• x < 5

• x < 7

Find the value of the series: 1/2 + 1/4 + 1/8 + 1/16 + ...

• 2

• 3

• 4

• 1
