The value of (tan29°cot61°-cosec261°)+cot254°-sec236°+(sin21°+sin23°+sin25°+.....+sin289°) is:
If sin(A+B-C) = cos(A+C-B) = tan(B+C-A), then the value of angle A is
In a triangle ABC, right-angled at C, if \(sec A={13\over5}\), then find the value of \(\frac{1+ \sin A}{\cos B}\).
If x & y are acute angle, x+y <90° & sin(2x - 20°) = cos(2y + 20°), the value of sec(x + y) is
