Find the general solution for:-

~Please show your work

~Thank you!

Step-by-step explanation:

we would like to solve the following trigonometric equation:

the left hand side can be rewritten using angle sum indentity of sin which is given by:

therefore Let

Thus substitute:

simplify addition:

keep in mind that sin(t)=sin(π-t) saying that there're two equation to solve:

take inverse trig and that yields:

add π to both sides of the second equation and that yields:

sin function has a period of 2nπ thus add the period:

divide I equation by 4 and II by -4 which yields:

recall that,-½(nπ)=½(nπ) therefore,

by using a calculator we acquire:

hence,

the general solution for: for the trig equation are

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
