Sin X Tan X

Sin X Tan X. PDF filevalues of x at which tanx is undefined tanx has both left and right vertical asymptotes Specifically if a is a value of x outside the domain of tanx then lim x!a¡ tanx = +1 and lim x!a+ tanx = ¡1 † Cotangent The function cotx is a lot like tanx It is defined at all values of x for which sinx 6= 0 In other words the domain of.

Proof of limit of sin x / x = 1 as x approaches 0 math

`sin theta =y/r` `cos theta =x/r` `tan theta =y/x` Notice that we are still defining sin θ as `”opp”/”hyp”` cos θ as `”adj”/”hyp”` and tan θ as `”opp”/”adj”` but we are using the specific x y and rvalues defined by the point (x y) that the terminal side passes through We can choose any point on that line of course to define our ratios To find r we use Pythagoras’ Theorem.

2. Sine, Cosine, Tangent and the Reciprocal Ratios

Ex 33 9 Prove cos (3π/2+????) cos (2π + ????)[cot (3π/2−????) + cot (2π + ????)] =1 Taking LHS First we solve cos (????????/???? “+ ” ????) Putting π.

Signs of sin, cos, tan in different quadrants Finding

Thus sin(90) = y = 1 and cos(90) = x = 0 The circle will look like this Fig 5 Unit circle showing cos(90) = 0 and sin(90) = 1 What about tangent(90)? As the cosine measure approaches 0 and it happens to be a denominator in a fraction the value of that fraction increases to infinity Therefore tan(90) is said to be undefined.
