Work: Find the solution of equation 0.2+aretan(31.825)*0.2/3.14 = 0 .
Question type: Equation
Solution:Original question:
1 5 | + | a | ( | 1273 40 | ) | × | 1 5 | ÷ | 157 50 | = | 0 |
| Left side of the equation = | 1 5 | + | a | ( | 1273 40 | ) | × | 10 157 |
1 5 | + | a | ( | 1273 40 | ) | × | 10 157 | = | 0 |
| Left side of the equation = | 1 5 | + | a | × | 1273 40 | × | 10 157 |
| = | 1 5 | + | a | × | 1273 628 |
1 5 | + | 1273 628 | a | = | 0 |
Transposition :
1273 628 | a | = | 0 | − | 1 5 |
Combine the items on the right of the equation:
1273 628 | a | = | - | 1 5 |
The coefficient of the unknown number is reduced to 1 :
| a | = | - | 1 5 | ÷ | 1273 628 |
| = | - | 1 5 | × | 628 1273 |
We obtained :
| a | = | - | 628 6365 |
Convert the result to decimal form :
| a | = | - 0.098665 |
