What is the value of tan90o? Trigonometric Functions: A sine function is a trigonometric function that relates the angle of the right-angled triangle to the ratio of the perpendicular and the hypotenuse. The trigonometric function at a specific angle can be computed with the help of the valu...
The number 100 is 10 more than 90. To find this answer, we can construct a more typical math problem based on the words in the sentence. We know our...
Trigonometry is an importantbranch of mathematicsthat is used to study the relationship between ratios of the sides of a right-angled triangle with itsangles. The word “trigonometry” is derived from the Greek words, “trigon” and “metron”. The word “trigon” means a triangle and the wor...
What is the value of [tan2(90−θ)−sec2(90−θ)]tan2(90−θ)cot2(90−θ)? View Solution Write the value of cosec2(90∘−θ)−tan2θ. View Solution Knowledge Check tan2(90∘−θ)−cosec2θ= A0 B1 C-1 D2Submit What is the value of [tan(90−θ)+sec(...
This explains why tan is undefined for 90° or −270° and 270° or −90° (where x = 0), because you can't divide by zero. Graphing Trigonometric Functions Graphing sin or cos becomes easier when you think of the unit circle. The x-coordinate varies smoothly as you...
