Write a code to compute a natural spline s(x) which interpolates a collection of given points (x0; y0); (x1; y1); : : : (xn; yn) where x0 < x1 < x2 < : : : < xn (do not assume they are equidistributed). your code should have a triadiagonal solver for the resulting linear system of equations (you're not allowed to use matlab's n operator to solve the linear system).

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

just pick what you think i need more time let me know if this
