Common Misconceptions in Trigonometric Ratios

Students often confuse the sine, cosine, and tangent ratios and their respective angles in the unit circle. Remember, sine is opposite over hypotenuse, cosine is adjacent over hypotenuse, and tangent is opposite over adjacent.

Incorrect Use of Special Triangles

Be cautious when using special right triangles (45-45-90, 30-60-90) to solve problems. Ensure you use the correct ratios and understand when to apply them.

Calculating Area of Irregular Shapes

When finding areas of irregular shapes, like trapezoids or triangles with base not parallel to the x-axis, ensure you calculate the area correctly by using the formula for the respective shape and considering vertical or horizontal shifts as needed.

Not Simplifying Expressions Enough

Always simplify your expressions and equations as much as possible before solving. This includes combining like terms, factoring, and simplifying fractions. A common mistake is rushing through calculations without ensuring the expression is in its simplest form.
Students often confuse the difference between sine, cosine, and tangent functions. They also struggle with the unit circle and applying the correct trigonometric ratios to solve problems.
