Understanding the Context

See all questions in trigonometric functions of any angle impact of this question Sec(x) = 1 cos(x) sec2(x) = (1 cos(x))2 = 1 cos2(x) = 1 (cos(x))2. Sec(π 4) = 1 (cos(π 4))2 ⇒ {cos(π 4) = √2 2} sec(π 4) = 1 (√2 2)2. Sec(π 4) = 1 22⋅1 2. Find the exact value sec (pi/4)^2.

Key Insights

Sec2 ( π 4) sec 2 ( π 4) the exact value of sec(π 4) sec ( π 4) is 2 √2 2 2. ( 2 √2)2 ( 2 2) 2. Multiply 2 √2 2 2 by √2 √2 2 2. ( 2 √2 ⋅. Use the following trivial identity.

Final Thoughts

An angle of π 4 can be represented as a standard triangle with adjacent and opposite side both = 1 and hypotenuse = √2. Webthe actual value of sec pi/4 is square root of 2 or simply 1. 414 in decimal form. Webthe value of sec pi/4 is 1. 4142135. Sec pi/4 radians in degrees is written as sec ((π/4) × 180°/π), i.

e. , sec (45°). In this article, we will discuss the methods to find the value of. \begin {cases} { 8x+2y = 46 } \\ { 7x+3y = 47 } \end {cases} \right.
