Question

How do you find a gradient on a line with a 45 degree angle?

Answer 1

you mean slope? it is 1

Answer 2

yeah a slope, it's going from bottom left to top right and it has a 45 degree angle from the x axis

Answer 3

i cant remember ;)

but I think its 1

Answer 4

but I have loads of questions on it and they can't all be 1 :/

Answer 5

each question probably has a different theme or subject to it; what are the questions?

Answer 6

the slope of a 45 degree angle; is 1

Answer 7

the slope is simply the tangent;

tan(45) = 1 right?

Answer 8

how do I know whether to use tan sine or cos?

Answer 9

sin tells you the y value

cos tells you the x value

and since slope = y/x ;

slope = sin/cos = tan

Answer 10

so that how you get the gradient?

Answer 11

the gradient of an angle is sin(a)/cos(a)

since sin/cos is how we define tan

teh gradient of an angle = tan(a)

tan(45) in this case = 1

Answer 12

THANK YOU!!

Answer 13

yep :)

Answer 14

do you know how to calculate the size of the angle a straight line makes with a positive direction of the x axis. when you have the equation y=2x-3
