use the formula sec A = 1/cos A and substitute θ =60 degrees for A to get sec60= 1/cos60. On the calculator, find cos 60 by pressing the "cos" function key and input 60 to get .5 and calculate the reciprocal 1/.5 =2 by pressing the inverse function key "x -1 " and ente...
error occurs when a formula attempts to calculate the intersection of two ranges that do not actually intersect. This can happen when the wrong range operator is used in the formula, or when the intersection operator (represented by a space character) is used between two ranges that do not ov...
The most common, and the one you might be the most familiar with is sin2(θ)+cos2(θ)=1, and the other two are tan2(θ)+1=sec2(θ) and cot2(θ)+1=csc2(θ). Constant Multiple Rule: The constant multiple rules for both definite and indefinite integrals ...
Carefully show how to simplify cot2x−csc2xcosx to get −secx. Simplifying Trigonometric Expressions: While simplifying trigonometric identities, the best strategy that we have at our disposal is to make optimum use of fundamental trigonometric identities. A ...
Step 1 - Calculate weekday number The WEEKDAY function converts an Excel date to a number 1 - 7 representing the weekday. WEEKDAY(C2) becomes WEEKDAY(43952) and returns 6. Friday is the sixth weekday in a week. The week begins with Sunday if you omit the second argument. 1 - Sund...
