Great Horned Owl fledgling hissing and clacking
Great Horned Owl fledgling found on a nature trail near Seattle Washington. Parents were nearby keeping a close eye (you can hear them hooting in the background). I filmed the encounter for a brief moment to record the interaction and quickly left, so as not disturb them for too long.

Trigonometric Identities | How to prove tan^2x-sin^2x=tan^2x*sin^2x
zhlédnutí 2,5KPřed 3 lety
A review of how to prove trigonometric identities. In this video, I demonstrate how to work through a more challenging flavor of this question type. Prove tan^2x-sin^2x=tan^2x*sin^2x
Trigonometric Identities | How to prove (1/(1-sin(x)) - (1/1+sin(x)) = 2sec(x)tan(x)
zhlédnutí 1,6KPřed 3 lety
This is a quick review of how to solve a trig identity problem that involves proving a given trigonometric equation. These problems come in a variety of flavors. The one I'm covering here is a good example of how to deal with questions like this that have multiple fractions on one side of the equation. (1/1-sinx) - (1/1 sinx) = 2secx*tanx

Gila Woodpecker foraging for food in Southern Arizona
zhlédnutí 72Před 7 lety
A Gila Woodpecker searches for insects tucked away within the bark on this tree. He uses his beak to edge into the cracks to obtain a tasty treat. You'll notice a red patch on the top of his head, too. This distinguishing characteristic is how one can easily identify a male or female. Females do not have this coloration on their crown.
Flowering Yucca Plant
zhlédnutí 2KPřed 9 lety
Throughout all of the desert flora I was able to find while in Arizona, it was this beautiful yucca plant that was the most memorable. I don't know exactly which species this is but it belongs in the family Asparagaceae. For me, it's significance lies within its tall stalk. After doing a lot of research, I have yet to come across a yucca trunk as tall as this one. It was growing in a garden man...

I found this baby Desert Tortoise roaming around the hotel I was staying at in Arizona. As he was trying to find a shady place to cool down, he managed to get himself turned upside down. Fortunately, he gets back over by himself.
