Nettet6. jun. 2024 · 3. tan4 θ + tan2 θ = sec4 θ - sec2 θ. Solution: L.H.S = tan4 θ + tan2 θ = tan2 θ (tan2 θ + 1) = (sec2 θ - 1) (tan2 θ + 1) [since, tan2 θ = sec2 θ – 1] = (sec2 θ - 1) sec2 θ [since, tan2 θ + 1 = sec2 θ] = sec4 θ - sec2 θ = R.H.S. Proved. 4. If A = 60° and B = 30°, verify that sin (A - B) = sin A cos B - cos A sin B. NettetThales of Miletus (circa 625–547 BC) is known as the founder of geometry. The legend is that he calculated the height of the Great Pyramid of Giza in Egypt using the theory of similar triangles, which he developed by measuring the shadow of his staff.Based on proportions, this theory has applications in a number of areas, including fractal … holiday inn express veracruz boca del rio

NettetProve that : sec 4θ−sec 2θ=tan 4θ+tan 2θ Medium Solution Verified by Toppr LHS= sec 4θ−sec 2θ =sec 2θ(sec 2θ−1) =(1+tan 2θ)(1+tan 2θ−1) ......... (Using Trigonometric … NettetSolve your math problems using our free math solver with step-by-step solutions. Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. NettetThe Pythagorean identity tells us that no matter what the value of θ is, sin²θ+cos²θ is equal to 1. This follows from the Pythagorean theorem, which is why it's called the Pythagorean identity! We can use this identity to solve various problems. Created by Sal Khan.
