Inverse trigonometric functions (class 10,11 maths)

Learn how to find a missing angle in a triangle using trigonometric ratios like sine, cosine, and tangent. When given a right triangle, identify the known sides (opposite, adjacent, or hypotenuse) relative to the missing angle. Use the appropriate ratio:
Sine (sin) = Opposite/Hypotenuse
Cosine (cos) = Adjacent/Hypotenuse
Tangent (tan) = Opposite/Adjacent
Apply the inverse trigonometric function (e.g., sin⁻¹, cos⁻¹, tan⁻¹) to calculate the angle. This method is perfect for solving real-world problems or geometry tasks. Follow along for clear examples and tips to master this essential skill!
