A particle moves in a straight line so that, t s after passing through a fixed point O, its velocity, v ms⁻¹, is give…
Find the equation of the tangent to the curve y = x³ + 2x² – 3x + 4 at the point where the curve crosses the y-axis.
Variables x and y are such that y = e^(2x) + e^(-2x).
The line y = x + 4 intersects the curve 2x² + 3xy − y² + 1 = 0 at the points A and B. Find the length of the line AB.
Given that A = (2 3 / 1 -5) and B = (7 4 / 2 8), calculate 2A,
In this question, (1 / 0) is a unit vector due east and (0 / 1) is a unit vector due north. A lighthouse has position…
