How do you integrate a constant?

theta and miu are constants

theta = 0.01305
miu = 0.0546
const = @(x) tan(theta + miu)
r = integral(constant,0,1)

[Jan]

The integral of a constant function is the size of the rectangle between the curve and the X axis: const * (1 - 0).

theta = 0.01305

theta = 0.0131

miu = 0.0546

miu = 0.0546

const = @(x) tan(theta + miu)+0*x

const = function_handle with value:
    @(x)tan(theta+miu)+0*x

r = integral(const,0,1)

r = 0.0678

I am doing this and it is telling me that the integral is an error.

[Torsten]

Don't forget the +0*x when integrating your constant function.

Or use

theta = 0.01305

theta = 0.0131

miu = 0.0546

miu = 0.0546

const = @(x) tan(theta + miu)

const = function_handle with value:
    @(x)tan(theta+miu)

r = integral(const,0,1,'ArrayValued',true)

r = 0.0678
