The first three nonzero terms of the Maclaurin series for the arctangent function are x−(1/3)x3+(1/5)x5. Compute the absolute error and relative error in the following approximations of π using the polynomial in place of the arctangent: a. 4[arctan(12)+arctan(13)]b. 16arctan(15)−4arctan(1239)

i would need to see the dot plot : )

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
