Cоnsider the heаt equаtiоn u t = u x x . {"versiоn":"1.1","mаth":"u_t=u_{xx}."}Determine which of the following functions are solutions to the heat equation for all x∈ℝ{"version":"1.1","math":"x∈ℝ"} and t>0{"version":"1.1","math":"t>0"} by writing YES on the corresponding blank line. Write NO of the function is not a solution. u 1 ( x , t ) = 1 {"version":"1.1","math":"u_1(x,t)=1"} u 2 ( x , t ) = x {"version":"1.1","math":"u_2(x,t)=x"} u 3 ( x , t ) = x + t {"version":"1.1","math":"u_3(x,t)=x+t"} u 4 ( x , t ) = x 2 + 2 t {"version":"1.1","math":"u_4(x,t)=x^2+2t"} u 5 ( x , t ) = x 2 + t {"version":"1.1","math":"u_5(x,t)=x^2+t"} u 6 ( x , t ) = x 2 t + t 2 {"version":"1.1","math":"u_6(x,t)=x^2t+t^2"} u 7 ( x , t ) = x 3 + 6 x t {"version":"1.1","math":"u_7(x,t)=x^3+6xt"}
