-axis is your vertical "rise." Accuracy here prevents "math-burn" later in the problem. Key Formula When to Use Two Points When you have Point-Slope Best for Tangent Lines (Garis Singgung). Intercepts When the line crosses both axes.
(Based on: "Tentukan Persamaan Dari Fungsi Pada Gambar Tersebut") When you're staring at a graph, look for two "anchor points." Use the formula is the intercept on the y-axis and
(Based on: "Tentukan Pertidaksamaan Yang Tepat") Equations tell you where the line is ; inequalities tell you where the region is. If the region is a solid line, it’s ≥is greater than or equal to If it’s below , it’s ≤is less than or equal to Pro Tip: Always use as a test point. If -axis is your vertical "rise
(Based on: "Contoh Soal Persamaan Garis Singgung Kurva Trigonometri") This is where calculus meets geometry. To find the "Garis Singgung" (tangent line): Take the derivative of the trig function ( Plug in the Point: Use the given angle (e.g., ) to find your slope. The Formula: Use 3. Shading the Truth: Linear Inequalities
makes the statement true, shade the side containing the origin! (Based on: "Tentukan Persamaan Dari Fungsi Pada Gambar
is the intercept on the x-axis. It’s the fastest way to turn a drawing into an equation.
Determining the equation of a line (Persamaan Garis) is the bread and butter of coordinate geometry. Whether you’re looking at a simple straight line or a curve’s tangent, the logic remains the same: it’s all about the relationship between To find the "Garis Singgung" (tangent line): Take
