1.. Calculate the equation X1 2X2 3X3 = 1 5x1 x2-3x3 = -4 7 x1 8x2 11x3 = -3 printout calculation results to write programs 2 with C language. Sin0.32 = 0.314567, sin0.34 = 0.333487, SIN0.36 = 0.352274, the approximation of SIN0.3367 is calculated using a linear interpolation and secondary interpolation, and the output calculation results, the younger brother is thank you, help I!
