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...

4. Use the Sine Rule: According to the sine rule, we have: asinA=bsinB=csinC From this, we can express a, b, and c in terms of sinA, sinB, and sinC: a=ksinA,b=ksinB,c=ksinC where k is a constant. 5. Substitute a, b, and c into the expression: =(ksinA−ksinC)sinB...
