Test Status Code Input and Output
1   Pass
f = @(x) -x; tf =1; y0 =1; assert(abs(deqnsolve(f,y0,tf)-exp(-1)) < 1e-5)

res = 0.3679

2   Pass
f = @sin; tf =1; y0 =1/2; assert(abs(deqnsolve(f,y0,tf)-2*acot(exp(-1)*cot(1/4))) < 1e-5)

res = 1.2135

3   Pass
f = @(x) 1/(x+1); tf =6; y0 =1; assert(abs(deqnsolve(f,y0,tf)-3) < 1e-5)

res = 3.0000

4   Pass
a = rand*0.9; f = @(x) x-a*x^2; tf = rand+1.5; y0=1; assert(abs(deqnsolve(f,y0,tf)-exp(tf)/(1-a+a*exp(tf))) < 1e-5)

res = 1.8297
