Evaluate : cos(270° -θ) Answer : To evaluate cos(270° -θ), we have to consider the following important points. (i)(270° -θ) will fall in the III rd quadrant. (ii) When we have270°, "cos"will become "sin" (iii) In the III rd quadrant, the sign of "cos" is negative...
The main thumb rule to score well in Trigonometry is to learn your Pythagoras theorem with a whole heart. Keeping the Sine rule and CoSine rule at your fingertips will help you solve any type of problem in the examination. Finally, list down all the important identities and formulas of Trigo...

Sin and Cos are two of the most fundamental trigonometric ratios and they are also the most widely used trigonometric ratios. It is because, using these trigonometric ratios, we can derive the reset of the trigonometric values, such as Tan, Cot, etc. So, learning the values of these ratios...

Step 2: Substitute Sine and Cosine Values From the sine rule, we know that: asinA=bsinB=csinC=k(some constant). This gives us: sinB=bk,sinC=ck. For cosine, we use the cosine rule: cosC=a2+b2−c22ab,cosB=a2+c2−b22ac. Step 3: Substitute into the Expression Now substitute these...
how many 意为“多少”,修饰可数名词复数形式,所以 rule 用复数形式。故正确答案为 rules。2. 结合文意,在一些学校,学生们上学时必须(have to)穿校服。have to 是固定搭配,意为“不得不,必须”。故正确答案为 have。3. 结合文意,学生们不喜欢校服,认为校服是世界上最丑的衣服(clothes)。clothes 意为“...
