1) Using a calculator or graphing software, we can see that the equation 4sin(x+30)=3 has two solutions in the given interval: x ≈ 25.67° and x ≈ 319.67°.
2) We can rewrite the equation sin(2-100)=0.5 as sin(-98)=0.5. Then we can use a calculator or the unit circle to find the solutions in the given interval: x ≈ 172.12° and x ≈ 347.88°.
3) We can rewrite the equation 2sin^2(x-30)=cos60 as sin^2(x-30)=1/4cos60. Using the identity sin^2(x)+cos^2(x)=1, we can substitute cos^2(x)=1-sin^2(x) and simplify:
sin^2(x-30)=1/4(1-sin^2(60))
4sin^2(x-30)=1-1/4
4sin^2(x-30)=3/4
sin^2(x-30)=3/16
sin(x-30)=±sqrt(3)/4
Using the unit circle or a calculator, we can find the solutions in the given interval: x ≈ 67.77° and x ≈ 112.23°.
4) We can rewrite sin(x+30)=cos(2x) as sin(x+30)=sin(90-2x). Using the identity sin(a)=sin(b) implies a = n180 ± b for some integer n, we can solve for x:
x+30 = n180 - (90-2x)
3x = -120+180n
x = -40+60n
For 0<x<90, the only solution is x ≈ 50.33°. We can then use the identity cos^2(x) = 1-sin^2(x) to find cos^2(3x) ≈ 0.107.
5) We can rewrite the equation 4sin^2(0)+4cos^2(0)=5 as 4sin^2(0)+4(1-sin^2(0))=5 and simplify:
sin^2(0)=1/2
sin(0)=±sqrt(2)/2
Using the unit circle or a calculator, we can find the solutions in the given interval: x ≈ 45° and x ≈ 315°.
6) We can rewrite the equation 2sin^2(x)-1=cos^2(x)+sin(x) as 2sin^2(x)-cos^2(x)=1+sin(x). Using the identity sin^2(x)+cos^2(x)=1, we can substitute cos^2(x)=1-sin^2(x) and simplify:
2sin^2(x)-(1-sin^2(x))=1+sin(x)
3sin^2(x)+sin(x)-2=0
(3sin(x)-2)(sin(x)+1)=0
The solutions in the given interval are x ≈ 40° and x ≈ 180°.

#1
4sin(x+30)=3
sin(x+30) = 3/4
using my calculator, as did the bot
x + 30 = 48.6° or x+30 = 131.4
x = 18.6° or x = 101.4° , the bot is wrong
#2
sin(2-100)=0.5 <------ looks like a typo, has to be fixed
#3
2sin^2(x-30)=cos60
2sin^2(x-30)=1/2
sin^2(x-30)= 1/4
sin(x-30) = ± 1/2
x - 30 = 30 or x - 30 = 150
x = 60° or x = 180° , the bot is wrong again , it gives a gibberish solution
#4
sin(x+30)=cos2x^0 <---- looks like another typo, the bot gives a gibberish solution
#5
4 sin ^20+4cos0=5 , assuming you mean
4 sin ^2 θ+4cosθ = 5
4(sin ^2 θ + cosθ) = 5
4(1 - cos^2 θ + cosθ) = 5
-4cos^2 θ + 4cosθ -1 = 0
4cos^2 θ - 4cosθ + 1 = 0
(2cosθ - 1)^2 = 0
2cosθ = 1
cosθ = 1/2
θ = 60° or x = 300° , as expected, the bot is wrong again.
#6
noticed that after 2sin^2(x)-(1-sin^2(x))=1+sin(x)
the bot screwed up again.
Let's see if it can find its mistake

So the bot is just repeating my solutions again???
I called it out previously and accused it of plagiarism.
In #2, betsy did not correct the typo, but the bot made something up, lol
#6, the bot simply repeated its incorrect solution, did not correct its error
