I am relatively new to Maple, and have been attmpting to solve this for the last few days, and if somebody would be able to help me out that would be great. I am attempting to make the list of following equations smooth (supposed to be for a roller coaster): u(x)=.8x (where x is less than 0) g(x)=kx^3 + lx^2 + mx + n (where is is greater than or equal to 0 but less than 10) f(x)=ax^2 + bx + c (where x is greater than or equal to 10 but less than or equal to 90) h(x)=px^3 + qx^2 + rx + s (where x is less than 90 but greater than or equal to 100) t(x)=-1.6x + 120 (where x is greater than 100)
