You can do each calculation separately and do all the math, or you can recognize the angle difference formula for cosine: cos(A-B)=cosAxxcosB+sinAxxsinB In this case, A is 60^@ and B is 30^@. Aug 16, 2023 · Transcript. Ex 8.2, 1 Evaluate the following : (i) sin 60° cos 30° + sin 30° cos 60° We know that, sin 60° = √3/2 cos 30° = √3/2 sin 30° = 1/2 cos 60° = 1/2 Putting all values sin 60° cos 30° + sin 30° cos 60° = (√𝟑/𝟐)× (√𝟑/𝟐)+ (𝟏/𝟐)× (𝟏/𝟐) = (√3 × √3)/ (2 × 2)+1/ (2 × 2) = 𝟑/𝟒 + 𝟏 ... Free trigonometric function calculator - evaluate trigonometric functions step-by-stepFree math problem solver answers your trigonometry homework questions with step-by-step explanations.これらは sin (θ), cos (θ) または 括弧 を略して sin θ, cos θ と記述される（ θ は対象となる角の大きさ）。. 正弦関数と余弦関数の比を正接関数（タンジェント、tangent）と言い、具体的には以下の式で表される：. 上記3関数の逆数関数を余割関数（コセカント ... Firstly, we choose the cosine, i.e., cos (x) \cos(x) cos (x), from the list. Once we have that, we move to the variable field below, which contains the angle. We input 45 ° 45\degree 45° from our problem, and the moment we do that, the cofunction calculator will spit out the answer underneath: the cofunction along with the value.The three main functions in trigonometry are Sine, Cosine and Tangent. They are just the length of one side divided by another. For a right triangle with an angle θ : Sine Function: sin (θ) = Opposite / Hypotenuse. Cosine Function: cos (θ) = Adjacent / Hypotenuse. Tangent Function: tan (θ) = Opposite / Adjacent. Find the Exact Value cos(-60 degrees ) Step 1. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Step 2. The exact ...Free trigonometric function calculator - evaluate trigonometric functions step-by-step .
