y = 11/21
To solve this first evaluate the power (then calculate the sum):
<u><em>
</em></u>y - <u><em>
</em></u> = 5y +<u><em> (-5 + 7)</em></u>
16y - 9 = -5y + 2
Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):
16y <u><em>- 9 </em></u>= <u><em>-5y</em></u> + 2
16y + 5y = 2 + 9
Next Collect the like terms and calculate the sum:
<u><em>16y + 5y</em></u> = <u><em>2 + 9</em></u>
21y = 11
Lastly divide both sides of the equation by 21:
<u><em>21y = 11</em></u>
y =

Step-by-step explanation:
Hello:
Use implicit differentiation : <span>y sin 12x = x cos 2y
y' sin12x+12ycos12x =cos2y -2x y'sin2y
when : x = </span>π/2 and y =π/4<span>
</span>y' sin12(π/2) +12(π/4)cos12(π/2) =cos2(π/4) -2(π/2) y'sin2(<span>π/4)
</span>y' sin(π/6) +(π/3)cos(π/6) =cos(π/2) - π y'sin(π/2)
y' (1/2) +(π/3)(√3/2) = - π
y' (1/2) =-(π/3)(√3/2) - π
y' = -π (1+√3)/3
an equation of the tangent line is : y- π/4 = ( -π (1+√3)/3)(x-<span>π/2)</span>
