How to add one polynomial to another using NumPy in Python? Last Updated : 29 Aug, 2020 Comments Improve Suggest changes Like Article Like Report In this article, Let's see how to add one polynomial to another. Two polynomials are given as input and the result is the addition of two polynomials. The polynomial p(x) = C3 x2 + C2 x + C1 is represented in NumPy as : ( C1, C2, C3 ) { the coefficients (constants)}. Let take two polynomials p(x) and q(x) then add these to get r(x) = p(x) + q(x) as a result of addition of two input polynomials.If p(x) = A3 x2 + A2 x + A1 and q(x) = B3 x2 + B2 x + B1 then result is r(x) = p(x) + q(x) i.e; r(x) = (A3 + B3) x2 + (A2 + B2) x + (A1 + B1) and output is ( (A1 + B1), (A2 + B2), (A3 + B3) ) Below is the implementation with some examples : Example 1: simple_use Python3 # importing package import numpy # define the polynomials # p(x) = 5(x**2) + (-2)x +5 px = (5,-2,5) # q(x) = 2(x**2) + (-5)x +2 qx = (2,-5,2) # add the polynomials rx = numpy.polynomial.polynomial.polyadd(px,qx) # print the resultant polynomial print(rx) Output : [ 7. -7. 7.] Example 2: #add_with_decimals Python3 # importing package import numpy # define the polynomials # p(x) = 2.2 px = (0,0,2.2) # q(x) = 9.8(x**2) + 4 qx = (9.8,0,4) # add the polynomials rx = numpy.polynomial.polynomial.polyadd(px,qx) # print the resultant polynomial print(rx) Output : [ 9.8 0. 6.2] Example 3: eval_then_add Python3 # importing package import numpy # define the polynomials # p(x) = (5/3)x px = (0,5/3,0) # q(x) = (-7/4)(x**2) + (9/5) qx = (-7/4,0,9/5) # add the polynomials rx = numpy.polynomial.polynomial.polyadd(px,qx) # print the resultant polynomial print(rx) Output : [-1.75 1.66666667 1.8 ] Comment More infoAdvertise with us Next Article How to add one polynomial to another using NumPy in Python?
