Question

. If A is the inclination of a line l then the slope or gradient of the line l is

(A) SinA (B) CosA (C) TanA (D) CotA​

Answer 1

Step-by-step explanation:

If θ is the angle of inclination of a straight line l, then tanθ is called the slope of gradient of the line is denoted by "m". (i) For horizontal lines, the angle of inclination is 0° or 180°. (ii) For vertical lines, the angle of inclination is 90°. (iii) For slant lines, if θ is acute, then the slope is positive.
