Giải phương trình: 2sin^2x-3cosx+1=0 với-2π

Simplifying

2sin2x + 3cosx + 1 = 0

Reorder the terms:

1 + 3cosx + 2in2sx = 0

Solving

1 + 3cosx + 2in2sx = 0

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-1' to each side of the equation.

1 + 3cosx + -1 + 2in2sx = 0 + -1

Reorder the terms:

1 + -1 + 3cosx + 2in2sx = 0 + -1

Combine like terms: 1 + -1 = 0

0 + 3cosx + 2in2sx = 0 + -1

3cosx + 2in2sx = 0 + -1

Combine like terms: 0 + -1 = -1

3cosx + 2in2sx = -1

Add '-2in2sx' to each side of the equation.

3cosx + 2in2sx + -2in2sx = -1 + -2in2sx

Combine like terms: 2in2sx + -2in2sx = 0

3cosx + 0 = -1 + -2in2sx

3cosx = -1 + -2in2sx

Divide each side by '3osx'.

c = -0.3333333333o-1s-1x-1 + -0.6666666667in2o-1

Simplifying

c = -0.3333333333o-1s-1x-1 + -0.6666666667in2o-1

Reorder the terms:

c = -0.6666666667in2o-1 + -0.3333333333o-1s-1x-1

Step-by-step explanation:

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
