I need help on finding the local linear approximation of tan 62 degree. i got 1.77859292096 can someone check if i got it right? tan(60+2) = (tan 60+ tan 2) / (1- tan60 tan 2) But tan2 appx = sin 2deg = sin2PI/180= 2PI/180 tan 62=(tan 60+2PI/180) / (1- tan60 2PI/180) check ...

solve 2x^2+3x+8=0 and express the solutions in a+bi form. Let's use the quadratic formula to solve for x and express those solutions in a+bi form. x = [-b + or - sqrt(b^2 - 4ac)]/2a Note: sqrt = square root. a = 2, b = 3, and c = 8 from your problem. Therefore: x = [-3 + ...

find an equation for a ploynomial function with zeros, negative 8, negative 3 over 4, 1 over 5, and 2. hey it is 53h8kkds f (x) = x(x+8)(x+ 3/4)(x- 1/5)(x-2) will be zero when any one of the factors is zero. Multiply the factors to get the polynomial form.

a square + b square = 80 ft (c Square) Through trial and error I can tell you that 6 squared (36) and 12 squared (44)are what you're solving for, but I just used trial and error to figure it out. 12 square is 144, not 44 a and b can be a combination of many numbers. For ...

NH3(aq) --> NH4OH NH4OH + CuCl2 --> Cu(OH)2 + NH4Cl First a massive precipitate forms (the copper hydroxide), however as more ammonia is added the equilibrium shifts to the diaquatetrammine copper(II) complex. Your best guess: CuCl2(aq) + 6NH3(aq) -->[Cu(NH3)4(H2O)2]2...
