My Answers :
1:
a x= 1/10 (9√41) ≈0.259688,Or x=1/10 (9+√41)≈1.54031
b:y=0 Or y=7/3
c: didn't solve.
d: t= 1/3 log(5/2)≈0.30543
e::β=3/5 Or β=3/5
2: didn't solve.
3:sin^1(√5/4)≈0.59
tan (0.59)≈0.67
4: didn't solve
5:sin(α)+cos(α)=4/3
We solve the equation
α= 2tan^1(1/7 (3√2))〗
We calculate sin(2α)
sin(2α)=7/9
6:max{f(x)=x^35x^28x+12}=400/27 at x=2/3
7:
a: 0
didn't solve b,c,d,e
8: The angle is 109.5 degrees
9:
a :: e^2x (6x^2+6xsin(x)+2 cos(x)+10)
b: 6y log(5)
c: secθ
d: 800
e: z( log(z)1)+constant
10 : didn't solve.
