Multiply: (2x^3-0.3)(2x^3+0.3)

please show me the steps on solving the problem-a general rule of conjugates is: (a + b)(a - b) = a² - b² So: (2x³ - .3) (2x³ + .3) = 4x^6 - .09

Differential Equation help ~

solve the differential equation sin x y-2y cos x =0 I want to know the steps, the answer is c sin^2 x, c is a constant-sin x y-2y cos x =0 so y * (sinx) = 2y cos x so y = 2y cos x /sinx = 2y cotx

The angle of elevation of the top of a building from a point on the ground 140 feet from the base

of the building is 62 degrees. Find the height of the building to the nearest tenth of a foot. Please show work!-tan(62)=ht/140 so, ht=140*tan(62)=263.3 ft

Solve the following equations: cos(2x) = -1/2 , 0 <= x <= 2π

a) cos(2x) = -1/2 , 0 b) 2sin(3x) - √3 = 0 , 0 -a) Set both sides by arccos and divide both sides by 2 to get: x = arccos(-½)/2 x = π/3, 4π/3, 2π/3, 5π/3 b) 2sin(3x) - √(3) = 0 Rearrange the term

How come this limit is equal 2

How come LiM of X that goes to plus INFINITE of( 2x + 1 ) OVER ( x - 2 ) is equal 2??????? Hows that possible? Shouldnt it be indeterminate?-(2x-1)/(x-2)= 2(x-2)/(x-2)+3/(x-2)= 2+3/(x-2) 2+3/(x-2)
