Web6sin (π/2⋅x) = 3. sin (π/2⋅x) = 1/2. From the unit circle, the sine values that equal 1/2 have the solution set x = π/6+2πn, 5π/6+2πn. π/2⋅x = π/6+2πn, 5π/6+2πn. x = 1/3+4n, 5/3+4n. Since we are looking for the 4 smallest positive solutions, we would need to plug in n=0 and n=1: x = 1/3+4 (0), 5/3+4 (0) x = 1/3, 5/3. x = 1/3+4 ... solo cup christmas light ball

WebApr 8, 2024 · There are 2 possible solutions to the equation. 2x −3 = ± (x + 2) first solution 2x −3 = x + 2 subtract x from both sides. 2x −x −3 = x −x +2 ⇒ x − 3 = 2 add 3 to both sides. x−3 +3 = 2 +3 ⇒ x = 5 second solution 2x −3 = −x − 2 ⇒ 3x = 1 ⇒ x = 1 3 As a check WebFeb 10, 2024 · 2x 2 = 32 3 Isolate the variable with the exponent by dividing both sides by the coefficient of the x term. In this case, 2 is the x coefficient, so divide both sides of the equation by 2 to get rid of it. Here's how: (2x 2 )/2 = 32/2 x 2 = 16 4 Take the square root of each side of the equation.
