Answer:
-2cos²(x) +3cos(x) -1
Step-by-step explanation:
Use the "Pythagorean identity" to replace sin²(x).
sin²(x) +cos²(x) = 1
Then ...
2sin²(x) +3cos(x) -3 = 2(1 -cos²(x)) +3cos(x) -3
= -2cos²(x) +3cos(x) -1
x = 4Rearrange:Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
1/8*x-(1/2)=0
Step by step solution :Step 1 : 1 Simplify — 2Equation at the end of step 1 : 1 1 (— • x) - — = 0 8 2Step 2 : 1 Simplify — 8Equation at the end of step 2 : 1 1 (— • x) - — = 0 8 2Step 3 :Calculating the Least Common Multiple : 3.1 Find the Least Common Multiple
The left denominator is : 8
The right denominator is : 2
the answer is 4
Step-by-step explanation:
-3+2y<4x
then
2y< 4x+ 3 (add both sides with 3)
y < 2x +3/2 ( divide both sides by 2 that is positif and we do not change the sens < )
Hope you understand.
