The sine function of an angle is equal to the opposing side's length divided by the hypotenuse side's length, and the formula is as follows: \[sin\theta =\frac{\textrm{opposite side}}{\textrm{hypotenuse side}}\] The sides of a triangle are proportional to the sine of the opposite an...
To solve the problem, we need to analyze the expression given and determine if it is equal to the specified value. We will break it down step by step.Step 1: Understand the Given Expression We have the expression: \( \frac{(2\t

sin(L)−cos(90∘−L)? (1) 1. (2) 0. (3) L. (4) -L.Cofunctions Identities in Trigonometry:When the two other angles of a right triangle are added together, a right angle is formed, which can be used to derive the identities ...
Let us assume that $\theta = 18^\circ$ ….(1) We have to analyse the problem as to how we can write standard angles such as 180 in terms of the 18. Here, we can write 18 in terms of 90 since sin 90 will be equal to 1. This step is followed in order to simplify the solut...
