3.3 坐標正算

private void button1_Click(object sender, EventArgs e){double x1 = double.Parse(textBox1.Text);double y1 = double.Parse(textBox2.Text);double rad = double.Parse(textBox5.Text);double distance = double.Parse(textBox6.Text);textBox3.Text = Convert.ToString(x1 + Math.Cos(rad)*distance);textBox4.Text = Convert.ToString(y1+Math.Sin(rad)*distance);}

3.4 坐標反算

3.5 角度前方交會

private void label8_Click(object sender, EventArgs e){double x1 = double.Parse(textBox1.Text);double y1 = double.Parse(textBox2.Text);double x2 = double.Parse(textBox4.Text);double y2 = double.Parse(textBox5.Text);double α1 = double.Parse(textBox3.Text);double α = radtodms(α1);double β1 = double.Parse(textBox6.Text);double β = radtodms(β1);double Z1 = x1 / Math.Tan(β) + x2 / Math.Tan(α) - y1 + y2;double D = 1 / Math.Tan(α) + 1 / Math.Tan(β);double Z2 = y1 / Math.Tan(β) + y2 / Math.Tan(α) + x1 - x2;double x3 = Z1 / D;double y3 = Z2 / D;textBox7.Text = Convert.ToString(x3);textBox8.Text = Convert.ToString(y3);}

3.6 角度后方交會

private void button1_Click(object sender, EventArgs e){double x1 = double.Parse(x1_textBox1.Text);double y1 = double.Parse(y1_textBox2.Text);double x2 = double.Parse(x2_textBox3.Text);double y2 = double.Parse(y2_textBox4.Text);double x3 = double.Parse(x3_textBox5.Text);double y3 = double.Parse(y3_textBox6.Text);double α = double.Parse(textBox7.Text);double β = double.Parse(textBox8.Text);double γ = double.Parse(textBox9.Text);double A = Math.Atan((y3 - y1) / (x3 - x1)) - Math.Atan((y2 - y1) / (x2 - x1));double B = Math.Atan((y1 - y2) / (x1 - x2)) - Math.Atan((y3 - y2)/(x3-x2));double C = Math.Atan((y2 - y3) / (x2 - x3)) - Math.Atan((y1 - y3) / (x1 - x3));double P1 = 1 / ((1 / (Math.Tan(A))) - (1 / Math.Tan(α)));double P2 = 1 / ((1 / (Math.Tan(B))) - (1 / Math.Tan(β)));double P3 = 1 / ((1 / (Math.Tan(C))) - (1 / Math.Tan(γ)));double x4 = (P1 * x1 + P2 * x2 + P3 * x3) / (P1 + P2 + P3);double y4 = (P1 * y1 + P2 * x2 + P3 * y3) / (P1 + P2 + P3);x4_textBox10.Text = Convert.ToString(x4);y4_textBox11.Text = Convert.ToString(y4);}

3.7 距離交會
